Engine

An automatic Idle Speed Control (ISC) system is integrated into each throttle body, and produces stable idle while improving cold starting and reducing emissions immediately after start up. Each 39mm throttle body carries a 10-hole fuel injector. The extra-fine atomization injectors produce an average spray particle diameter that is smaller for improved combustion efficiency. Suzuki Composite Electrochemical Material (SCEM) liner reduces friction and improves heat transfer, durability and ring seal. 645cc displacement with a bore and stroke of 81.0mm x 62.6mm and a compression ratio of 11.5:1. New single valve springs reduce inertia weight and mechanical losses while maintaining accurate valve control. Conventional pressed in iron liners are replaced with Suzuki’s own race proven nickel-phosphorus-silicon-carbide coating (SCEM), which reduces friction and improves heat transfer, durability and ring seal.
