Comments On Aug 14, 2012:My dad just put one of these on his crf450r to try and help with the overheating problem and he loves it so far! Around our property and in the desert (casually riding) it runs a little bit cooler than before but we have a race in wendover coming up (way hot) and that will be the ultimate test. Hopefully I can get back on here and let you guys how it did. The flywheel also helps it run a lot smoother and not die as easy

Comments On Sep 20, 2011:It was a must on my 07 crf 450. Made pounding out tight single track much easier. Less stalling, more lugging, and smoothed out the power for me. Love it.

Comments On Oct 13, 2010:I have a 2007 crf 450r and I bought the 33oz so I wouldn't have to mess with anythang, but still had to trim on the cover to get to fit without hitting. Also bought the cheep puller that worked great but a air wrench makes it a breez. Just also raced a hare scramble with it and the diffrence was unreal. Instead of hitting a hill wideopen. You can just torque over it!

Comments On Nov 20, 2009:Didn't think I need one on my bike but it made a diffrence. Less clutch work, less stalling, more power to the ground. I'd recommend for anyone riding tight singletrack.

Comments On May 01, 2008:GREAT!! I installed the 31oz on a 2006 Honda CRF250X. If you trail ride it's greatt it takes the punch out thats a bummer but you can start off and not even give the bike gas or kill it hooks up better if you want lug power it's for you

Comments On Oct 22, 2007:Wow, what a great addition to my 2006 CRF450. Makes the bike hook up so much better out of turns and on jump faces. No worries of stalling during big air jumps with an extra 13 oz of spinning mass.
Fit/Finish was perfect.
I am several seconds faster per lap with this flywheel!
