Check out action and component photos of the 2012 Yamaha WR250F Project Bike from our testing in Southern Oregon.
- The Fatbar handlebars are crafted from 7010-T6 aluminum with a 1-1/8” center clamping section.
- The added decibels make for a nice, throaty sound but the bike will still pass our local tech inspections with the quiet insert installed.
- We are able to clutch the front end over obstacles without as much effort and the bike picks up throttle without the clutch much better.
- Both of our testers noted an increase in power across the rpm spread. The WR is much easier to ride in a higher gear with the Leo Vince system and the change in sprockets help boost the Yammie’s grunt as well.
- The aftermarket slip-on weighs 6 lbs., 14.2 oz. compared to the stock unit at 7 lbs., 8.8 oz. Our Leo Vince-equipped WR blew 95 dB using the standard 20-inch stationary test. The stock pipe is good for 89 decibels.
- The Leo Vince pipe is supposed to come with a graphite spacer to connect the muffler to the header. Ours did not come with the spacer.
- To help compensate for that low-end bog and boost the ride-ability of third and fourth gears out on the trail we went one tooth larger than stock jumping up to a 51T.
- The Kevlar-reinforced grips use the half-waffle pattern but the base material contains Kevlar-brand resin particles.
- Renthal Moto Handguards protect against trail brush and roost.
- MotoUSA test rider Brian Chamberlain won the Amateur class main event at the endurocross race and it was in a spot to finish well in the 30+ main also until a small tip-over resulted in becoming traction for another rider.
