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 no Yamaha R1 fan is stranger to MotoGP, Yamaha Motor France offers, with the occasion of the Grand Prix of France (15-17 May), four limited edition replicas of the bikes raced by Valentino Rossi and Jorge Lorenzo.
Featuring nothing special apart from the racing paintjobs and a corresponsive free replica helmet, the bikes come with a price of 19,990 euros which translates into US$26,600.
Motociclismo states that Yamaha is developing a new T-Max from their currently successfully selling 500 model, a 750cc version supposedly powered by a three-cylinder motor specially designed for the new maxi scooter.
If the picture accords to Yamaha’s idea of a future 750 scooter, we’re happy to help spread the good news and dare ask your opinion about it.
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.
European fans of the Yamaha MT-01 are offered a 2009 limited edition version called SP in the manufacturer’s attempt to enhance the riding experience while also making the bike more attractive. So while the engine remains the same 1,670cc V-twin developing 90 horsepower at 4,750rpm and 150Nm of torque at 3,750rpm, the fork is now a fancy 43mm USD Öhlins unit and the rear shock an adjustable Öhlins one. These, together with the 17-inch wheels now featuring Pirelli Diablo Rosso tires – 120/70 front and 190/50 rear – are, according to Yamaha, supposed to offer ‘a more intense experience of ‘Kodo,’. Synthesizing, this means more heart beats per second.
