Burgman's motor

The Burgman's motor was given some serious upgrades. The motor was stroked to yield an extra 15cc, so it's a genuine 400 now. More importantly, the cylinder head was redesigned to make it dual overhead cam rather than SOHC. The fuel injection system gets a new 38mm throttle body and idle speed control system. A new exhaust system and emissions equipment clean up icky hydrocarbon residue. All these improvements improve power delivery (even if they don't increase power much) and reduce emissions, according to Suzuki. It's clean enough to pass both the strict Euro3 and CARB 2008 emissions laws. The chassis has also received improvements. It's still made of thin-walled high-tensile steel tubing, but it's now wrapped in a slightly larger, sleeker package. The windscreen is reshaped, along with the headlights and other plastic. The front wheel is now a 14 incher (were we crass we would make a crude joke here, but we will refrain) with dual 260 mm brake discs with two-piston calipers instead of a single disc with a four-piston caliper like last year's.
