In 2010, Yamaha plans to rule all competitions involving 450cc dirt bikes with their entirely redesigned YZ450F model. This is a bike that with ingenious engineering solves a big problem for all bikes in its category – space. It features a reversed cylinder engine allowing the entire reorganization of the engine bay and it is all mounted on a completely new, lighter frame. The rest is just a matter of finesse and it is all covered in the following article.
The Yamaha YZ450 is one of the best motocross bikes now around and little did we knew it can be adapted to a whole lot of riding conditions and even be turned into a 60’s style café racer if someone’s got the energy to undergo the demanding process of making a fact out of an innovative idea such as the oil-in-frame, just to give an example. The bike also features drilled engine plates and underseat pipe, but you’ll only notice that if you’re interested enough to look beyond the sleek fairing.
It is too bad we don’t have more information about this unique combination of style called YZ450 café racer as it was surely a bright idea and an exciting project.
Yamaha’s 2010 YZ85 stands out as one of the best means to power you from mini bikes to the real think. Even though it still is an evolutionary step in an ambitious rider’s career, this is the bike on which the first racing skills are being developed and that’s all that matters sometimes.
A smaller replica of the YZ250 and YZ125, the revised two-stroke model is sure to be a great success because no matter what you’ll do, it doesn’t manage to stay behind even if you play around with palls on bigger, but not smokier rides.
Designing a dirt bike is never easy, but it seems that Yamaha has got the perfect recipe as it pulls it through, managing to release better performing competition bikes with each year that passes. For 2010, the YZ125 carries on further perfecting its already great features such as the engine and chassis. Even though not the most important model year because the bike was great from the very beginning, it does catch our attention once again and that is never a bad thing.
Looking for a quarter-liter two-stroke dirt bike? Well, find out that the YZ250 is one of the most appreciated models in Yamaha’s 2010 motocross lineup not only for being designed to win with its YPVS Power valve-equipped two-stroke engine claimed to perform better than any previous generation, but because two-stroke motors are a very rare breed nowadays. Still present, this one is housed in a light aluminum frame, which allows it to turn the machine into an even greater blast out on the track, especially now that it is being fitted with ProTaper aluminum handlebars and Excel rims.
Given the fact that the motorcycle press has long shown the reverse-cylinder 2010 Yamaha YZ450F and, implicit, destroyed the maker’s element of surprise regarding this model, Yamaha has come up with a video showing James Steward as the inside man answering to ridiculous rumors heard by Yamaha employees, including Jorge Lorenzo, Valentino Rossi and James Toseland.
The video is supposed to create some buzz about this new model and to announce the launch date – September 8th.
Yamaha has released a video explaining the modifications done to their quarter-liter motocrosser of latest generation, the YZ250F. The bike now features a bilateral beam frame, while the engine now benefits of new valve train, carburetor and exhaust.
Overall, the new 2010 Yamaha YZ250F is supposed to offer a new riding position, handle sharper and deliver a more power with less noise. Sounds tempting to me!
This may not be the latest commercial that Yamaha made for their dirt bike lineup, but it sure is the most inspiring seen yet. Looking at it, most riders feel like gearing up and hitting the dirt on whatever model they got and that’s precisely what I’m planning to do now.
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.
The 2009 MX Championship has already started getting riders, motorcycles and their crews in trouble. These are by far the coolest pictures we’ve come across yet and by the small unstained blue on the front fender, we can confidently say that we’re dealing with a Yamaha dirt bike.
Apparently, as the bikes become better performing, organizers make sure that tracks are even harder to race on and that’s what the audience loves about motocross racing.
