2010 Suzuki RM-Z450 User Ratings

No big news like the 250’s switch to EFI in the RM-Z450’s camp, but it doesn’t mean that Suzuki hasn’t been busy dialing in and improving on its big MX bike. Modifications to the 2010 RM-Z450 engine include revised cam profiles, cylinder-head porting, and an improved camchain tensioner. Suzuki has also tinkered with the RM-Z450’s electronic fuel injection, reversing the throttle valve movement.
