BMW Scrambler Arriving in Late 2016






BMW just created a cost effective , a brand new range of stylish bikes based on the R nineT

With a Scrambler version leading the way , BMW are on the verge of revealing a range of lower cost R nineT-based bikes.

Two of the low-cost models are expected to arrive in late 2016, the Scrambler might arrive by the end of this year. The German firm keept no secrets of their intent to keep the air-cooled boxer engine in production, saying that they can easily meet ever-more stringent emissions regulations by keeping the state of tune relatively low.



The R nineT’s 110bhp and 88ftlb of torque is realistically the peak performance we can expect from the twin-cam head 8v motor. But where BMW have been notably clever is in extending the life of the engine by tailoring the applications it’s used in to fit its performance parameters, rather than trying to evolve the motor to fit ever-more demanding bikes.

The new liquid-cooled version of the 1200 boxer now is powering the GS, GSA, R, RT and RS, and the air-cooled version is off the hook to continue powering more characterful applications.



The R nineT has been a huge success for BMW, 8488 scramblers sold globally in 2014, making it the fourth most successful bike in their range behind the two leaders R1200GS, and the class-leading R1200RT.

BMW’s nineT is forming one of the cornerstones of the more expensive end of that scene with so much interest in the customisation scene, the factory have quickly latched on to the opportunity to sell pre-customised options. In addition, offering a lower cost blank canvas version for customisers opens the bike up to a whole new audience previously put off by the price of the nineT, and the thought of undoing BMW’s high-end work.


The expected ‘blank canvas’ versionwill be the lowest cost model . The roadster looks like will be familiar, the suspension, other cycle parts and tank will all be lower-spec than the nineT. BMW expect that most of these will be ripped apart to form the basis of myriad bobbers, café-racers, street trackers, and anything else in the range of custom-builders’ imaginations.



Sitting above this naked roadster will be two further models, just like Yamaha’s Sports Heritage range and Ducati’s four-bike range of new Scramblers, these two further models recognise that many buyers want the style and character, but don’t own the spanners, tig-welders and rattle-can skills to achieve the look. And perhaps have neither the time nor patience to effect such projects.

While no official images are available, we were able to get these pics based on descriptions from European dealers who expected this as a late 2015 model. The underpinnings are very clearly nineT, but with all the expensive elements supplanted by more basic ones, and styled to ape the early GS era.



Success will depend on BMW being able to hit the right price point, but dealers suggest that this is at the forefront of BMW’s plan. While the base model could cost nearly £7000, it’s more likely that the Scrambler will cost more like £8000, along with the other pre-styled version, which we believe will be a more café-racer orientated offering.

The excitement and immediate sales success of Ducati’s £6895–£7995 Scrambler will have been the driving force for BMW to rush out their take on the genre ahead of its siblings, but the arrival order post-Scrambler is less clear. It would seem likely that the other two models will arrive simultaneously during 2016, although possibly as late as the big European shows in the Autumn.



Why the delay?

Well the BMW production lines are already creaking under the massive increase in demand over the last few years, and with boxer engined bikes accounting for the top four sales figures in BMW’s range, it’s the busiest of all the production lines.

The R1200GS pairing achieved over 40,000 units last year, while the RT cleared another 12,140. In addition to those, 2015 sees the arrival of a completely redesigned and now water-cooled R1200R, and the re-introduction of the RS, also based around the new R1200 platform. It’s going to be another busy year, and the reinvigoration of the air-cooled range will remain key to the firm’s sales volume.

ELECTRIC TRUCKMAKERS * USA: Rather than burn fuel to drive wheels, the Wrightspeed generator-engine produces electricity

* California - Dawn of electric truck technology

-- The all-electric Tesla S car has wowed all who’ve driven it, and now the Kiwi co-founder of Tesla is working on a parallel feat by reinventing the truck powertrain... Ian Wright’s 'Wrightspeed' all-electric powertrains won’t revolutionise long-haul transport - that’s still a job for fossil fuels, Mr Wright said, or better, diesel-electric trains - but they are already transforming the operating costs of metropolitan haulage... “Here in the United States, the average Class 8 full-sized garbage truck is burning $55-$65,000 a year in fuel, and up to $30,000 in maintenance,” Mr Wright told Fairfax from his California headquarters. “Of that, we can save about $35,000 in fuel and $20,000 in maintenance. They are pretty substantial savings” ... On a big garbage truck, each drive unit is rated at 250 horsepower. On trucks with four drive wheels, the system has to be capable of generating enough electricity to produce 1000hp... A typical Wrightspeed-equipped garbage truck will get 30 miles (50 kilometres) out of an overnight plug-in recharge of its batteries. “Those are the cheapest miles, because electricity is very cheap compared to fuel,” Mr Wright said...

The 2015 YAMAHA FZ-07 Specifications & Price


Yamaha's new $6,990 FZ-07 takes a page from its FZ-09 big brother and improves upon it.

Now Yamaha has taken a page from the FZ-09’s design book by creating the new FZ-07, powered by an all-new midsize vertical twin utilizing the same 270-degree, crossplane firing order with its crankshaft.

The same innovative design and construction as its bigger brother is apparent throughout the FZ-07’s build, from its groundbreaking engine, the minimalist steel-tube frame and beautiful pressed-steel-sheet swingarm, to the horizontally mounted shock, 10-spoke cast-aluminum wheels and monoblock front brake calipers, etc. But best of all, that most-appreciated attribute from the FZ-09 is also carried over: an unbelievably low price, which for the FZ-07 is listed at $6,990.

We don’t know what they’re putting in the water over at Yamaha HQ in Japan, but we’re certainly hoping the spiking continues.

When Yamaha Motor Japan Senior Executive Officer Kunihiko Miwa stated at the 2012 Cologne show that the three-cylinder crossplane concept engine would be the basis for a new line of Yamaha sportbikes, we didn’t think that same philosophy would be used on a twin-cylinder powerplant (though perhaps looking back at Yamaha’s history would’ve reminded us that it’s not a new concept—anyone remember the TDM and TRX850 twins of the ’90s?).

The all-new 689cc parallel twin utilizes many of the same novel design ideas as its larger sibling besides the crossplane crankshaft, including offset cylinders (moved 7mm forward of the crankshaft centerline—the FZ-09’s are 5mm forward) to decrease piston/cylinder friction by reducing the angle of the connecting rod for more leverage during the power stroke.



Like the FZ-09, the FZ-07 engine’s gearbox is stacked to allow a more compact construction. Up top, Nippon electronic fuel injection with 38mm throttle bodies feed the 80.0 x 68.6mm engine, though in the probable interests of keeping price down, there is no ride-by-wire throttle setup as with the FZ-09.

The chassis may be made out of steel instead of the FZ-09’s aluminum unit to cut costs, but it’s hardly a second-rate build. The steel-tube backbone frame hangs the engine below as a stressed member, which not only permits a narrow midsection but also scales in 11 pounds lighter than the FZ6R frame. The swingarm is an asymmetrical unit made from pressed steel sheet of varying thickness; it’s a beautiful piece, and you’d hardly know it from an aluminum counterpart.

Throwing a leg over the FZ-07 reveals a nice low seat height that should appeal to most novice riders; it feels lower than the claimed 31.7 inches due to the very narrow front portion that makes it easier for those short of inseam to plant their feet at a stop. The overall ergos are much better than the FZ-09; the reach to the bars is not only shorter, but despite Yamaha’s claims of the conventional handlebar being set 24mm higher, it actually seems lower than the FZ-09’s setup that makes you feel like a windsail at 70 mph and above.

The only issue is that legroom is slightly less, so taller riders might feel a bit cramped.Suspension consists of a 41mm KYB conventional fork (non-adjustable) up front, with a preload-adjustable-only shock out back. In another innovative twist, the shock is horizontally mounted to the engine cases with a progressive linkage on the swingarm end, which saves weight and space. Braking is handled by dual 282mm wave-type discs and four-piston monoblock calipers, with the 10-spoke cast-aluminum wheels shod with either OEM-spec Michelin Pilot Road 3 or Bridgestone BT-023 rubber.

As befitting its intended (and likely) market, Yamaha let us sample the FZ-07 in the busy and gritty urban environs of metropolitan Seattle, as well as on some two-lane country-road jaunts on Bainbridge Island. In both these arenas, the crossplane-crank parallel-twin engine surprised us with its abundance of quick-revving torque that is much stronger than you’d expect for an engine of this size. Yamaha is claiming 50.2 foot-pounds at 6,500 rpm, and based on our butt dyno, we’d have no reason to doubt those claims.

There’s plenty of steam from down low to up top, and throttle response is butter-smooth in any situation. You can holeshot traffic with absolute ease, make a highway pass without having to tap dance on the shift lever, roost out of a tight set of corners with minimal fuss, or snap wheelies to your heart’s content in any of the first few gears as long as your skill and license are up to it. And it’s not just torque either; the Yamaha continues to generate surprisingly good power well into the upper reaches of its bar-graph LCD tachometer before the 9,900-rpm redline.



Matching that engine performance is a chassis that also surprised us with its competence. Overall handling is very agile without being twitchy, allowing you to put the FZ-07 exactly where you want with minimal effort. Despite its basic non-adjustability (save for spring preload in the rear), the suspension spring and damping rates at both ends are nearly spot-on for anything from cruising gnarled city pavement to spirited strafing runs down curving country roads. In fact, the FZ-07 actually feels more composed when the pace picks up in the twisties than its FZ-09 brother that has adjustable suspension. Ground clearance was more than adequate for the bike’s intended scope.


Aiding that composure (and performance) is the Yamaha’s incredibly light feel, and once again, the company’s claim of 397 pounds with a full tank of fuel doesn’t seem that far off the mark. Yep, you read that right; 397 pounds is 12 pounds lighter than Ducati’s air-cooled 696 Monster, almost 50 pounds lighter than Suzuki’s SFV650, and more than 60 pounds lighter than Kawasaki’s Ninja 650.

Braking is strong but novice-friendly, with a slightly soft initial response followed by a very linear progression of power. The amount of stopping power is directly proportional to how hard you squeeze the lever, meaning hard stops require a lot of lever pressure, with decent but not great feel.

Is there anything to gripe about with the new FZ-07? Well, we could mention the fuel tank only holds 3.7 gallons. Yamaha claims the bike has a 58 mpg average that allows it to have a greater range than the FZ6R with a 4.6-gallon fuel tank, but we’ll reserve judgment until we get our hands on a test unit and measure it ourselves.

After spending a day on Yamaha’s newest crossplane-crank creation, we couldn’t help but think of Suzuki’s original SV650, the firm’s gazillion-selling midsize V-twin that packed a similar combination of surprising performance and low sticker price. The SV didn’t have a lot of competition though, whereas now there are a good number of midsize bikes vying for the novice/intermediate rider who’s looking for a bike larger than 300cc on a limited budget.

No matter. We can definitely say this: Yamaha HQ in Japan better be sending an amply sized boat-full allotment of FZ-07s over to these shores. Because it is going to be selling a shipload of them.

TECHNO-TRAILERS * USA: SmartTruck TopKit

* South Carolina - SmartTruck TopKit offers 'Near-invisible" aero improvement for trailers
  --  SmartTruck Systems’ TopKit Fairing System, an innovative approach to aerodynamically increasing long-haul trucking fuel mileage, was confirmed to reduce aerodynamic drag by 10.5 percent in an independent study conducted by the SimCenter at the University of Tennessee at Chattanooga, it was announced today. The research independently confirms and quantifies TopKit’s performance in directly reducing the low pressure wake that creates drag behind all dry van trailers, refrigerated trailers, and straight trucks... The TopKit system was designed to provide a nearly invisible alternative to side skirts, boat tails and other devices that extend far from a trailer’s outside edges and create durability concerns as well as blocking access to the trailer for routine inspections and maintenance... The design of TopKit also eliminates the increased heating of tires and brakes that can result from the use of underside-based systems, according to the company, while SmartTruck’s top-based aerodynamic solution reduces the opportunity for damage from dock or intermodal operations...

DANGEROUS TRUCKS * USA: Half of the trucks, had overburdened tires because of heavy loads or low air pressure

* Michigan - Many tractor-trailers on Texas roads exceed tires’ safety ratings

-- Many tractor-trailers on the roads across Texas and the nation are driven faster than the 75 mph their tires are designed to handle, a practice that has been linked to wrecks and blowouts but has largely escaped the attention of highway officials... Nearly all truck tires have been built for a maximum sustained speed of 75 mph since the middle of last decade, when drivers across the vast majority of the U.S.A. were allowed to go no faster than 65 or 70 mph... But 14 states, mainly west of the Mississippi River, now have speed limits of 75, 80, even 85 mph in part of Texas. Some of those states acted without consulting the tire industry... Safety advocates and tire experts say that habitually driving faster than a tire’s rated speed can generate excessive heat that damages the rubber, with potentially catastrophic results... Last month, the National Highway Traffic Safety Administration closed the investigation into blowouts involving certain Michelin tires after determining that truck operators, not the tires, were at fault. As part of the Michelin investigation, the agency tested trucks and surveyed over a dozen drivers in Pennsylvania, finding that more than half had overburdened tires because of heavy loads or low air pressure. Sixty percent of drivers didn’t know the proper inflation pressure for the trucks they were driving...
