2010 Suzuki RM-Z250 Project Bike

2010 Suzuki RM-Z250 Project Bike

Suzuki racing technology is everywhere you look: advanced Suzuki fuel injection is fitted for the first time on a four-stroke 250cm3 Suzuki motocross machine. Further engine modifications boost peak power without giving up any of the low-end or midrange that has made the RM-Z250 the choice of top riders everywhere. Chassis updates improve handling with key suspension upgrades making the new RM-Z250 the perfect weapon for motocross racers worldwide. And there’s the eye-catching slim, aggressive styling that causes the RM-Z250 to stand out at any track. This, of course, brought about a few modifications to the engine. The core of the DOHC 249cc four-stroke remains the same, but it has undergone revised cam timing and updated its intake ports. Suzuki also went with a stronger connecting rod with mirror finishing and modified the crankshaft. The desired result of the changes is to give the 2010 RM-Z250 more oomph up top, which will be helpful since the switch to EFI has also added five pounds to its curb weight, up from 225 to 230.4 lbs. Chassis updates, suspension mods, a new muffler, the Suzuki R&D crew has been busy with its 250. The motorcycle that brought home the 2009 AMA Supercross Lites West Coast title should be a serious contender come shootout time. Until then, here’s a little of the Suzuki PR about the 2010 RM-Z250.
