Righto so the much awaited new WR450f has arrived so show us what you got, the mods you have done, tips & tricks. I got mine a few weeks back i plan on racing off-road with it but until the races come around I'm racing some MX on it and coming from a YZ450f its not that noticeable with the extra weight. Mods i have done so far; Remove the foam and kettle from the air box. Full FMF/GYTR Ti muffler and SS header lets it breathe i didn't even bother to start it with that pee shooter on it. Front and rear Excel wheels and hubs blue hubs and nipples black rims, I'm hard on wheels I don't even bother with stock wheels just throw them back on when i sell the bike and it looks good. 270mm GYTR/Braking front rotor its a really nice feel and the brakes are comparable to my 14 KTM450SXf Kroozetune 30mm lowering link really smooth's out the rear end I'm still working on it tho but love it over the stocko. GYTR high seat gives me better body position with the stock seat and the lowering link it felt really cramped. GYTR sprockets 14/50 think I'll go a 15/50 so i can hold second longer doing MX Rear 112mm race sag and i cant remember clicker settings once it bedded in I'll send it off and get it tuned, its still not right now. Obvioulsy removed all the speedo gear light etc. for doing MX. Tip if you put a header on it you need to feed it in from the right side, have to take the guard off the starter motor so it fits then put hex head bolts back in to bolt it up as you can't get an allen key in there with the FMF header.
