Those who were wondering what more could there be changed at Yamaha motocross bikes in order to improve performance are most likely to receive their answer with a single look at this spy picture of the 2010 Yamaha YZ450F reverse-cylinder.
This Powerpoint rendering shows how the new construction method allows the bottom end of the engine to move forward in the chassis, improving weight distribution and enhancing handling. This way, the exhaust pipe has a straight path towards the silencer and doesn’t need to be taken in consideration when doing the math for the front wheel clearance and also the inlet tract can be simply redesigned to go straight from the fuel injector to the combustion chamber. It even makes us wonder why Yamaha didn’t consider this possibility for the YZ450F so far.
Yamaha is supposed to unveil the completely new dirt bike within the next months and we reckon that it will blow away the competition.
Because Marines and militaries in general use public roads and motorcycles on which they don’t have much experience (sport bikes) to go in search of an adrenaline rush similar to that experienced as soldiers, the US Marine Corp has launched what is called “Semper Ride”, an educational program that consists in a very interesting film containing an overall responsible riding theme, instructional material, and mentoring from some of the motorcycle industry’s most talented riders.
We’ve added the promotional videos of the actual film because this last is for the moment watched in military bases only.
See the videos after the break.

KTM offers an enduro two-stroke trainer under the 200 XC-W name that stands for an impressively build motorcycle, always happy to provide an extremely accurate impression of what smokers are capable nowadays.
While the engine can be compared with at least a 300 cc four-stroke one, the bike weighs only 208.99 pounds without fuel, standing out as a possible blast. So where does beginner friendliness stand in this scenario? That’s what we’re about to find out.

KTM ensures that their faithful riders master those trails by offering a very difersified off-road lineup from which the XC-W model range distinguishes as being the most offering. The variety of both four-stroke and two-stroke models will leave nobody hiking and if we’re talking about riders who are just starting out, the 250 XCF-W is just the right thing to consider.

KTM has a two-stroke enduro alternative for each of their four-stroke model, so while the 250 XC-W is comparable to their 450 XC-W, what’s the 530 XC-W left with? The 300 XC-W, of course!
The big four-strokes have been seriously improved this year and the much smaller two-strokes simply had to keep up. And to be quite honest, the premises are totally favorable.

We often find ourselves wondering which will be a manufacturer’s next strategic move, but as much as we’d think it over, we wouldn’t have come to the conclusion that the Austrians from KTM might turn their attention towards the versatile 400 XC-W for 2009. Yet they did so and with excellent results. Now, we’re about to see how, in some cases, this bike stands out as an alternative for the
450 XC-W and even the
530 XC-W.
