Chassis Features - The New 2011 Yamaha MT-03's compact and minimalist frame is made from high-tensile steel tubing, and has been designed to give optimal rigidity for responsive handling and excellent rider feedback. This extremely strong design utilizes the 660cc engine as a stressed member, for extra solidity. The New 2011 MT-03 is designed to offer forward mass, where the rider sits closer to the handlebars than on conventional big singles for an idealized weight distribution and enhanced handling. This is accentuated by the supermoto-style forward riding position. The MT-03 has a lateral rear suspension, similar to the one first seen on the MT-01 concept bike. This design has the shock mounted almost horizontally on the right side of the bike, close to the engine. This makes the chassis slimmer around the mid-section and concentrates mass around the center of gravity for better handling. The MT-03 runs with newly-designed 5-spoke, 17 inch wheels, and their low weight ensures that the front and rear suspension work efficiently. At the front, a 120/70-17 tire grips the road, while an extra-wide 160/60-17 rear tyre delivers high levels of traction for strong back wheel drive force.
