i posted this in the CRF forum, i thought i would start a thread here. i have a 2006 CRF 450X ive been riding since new, and just bought a new WR450 here is what ive just posted on the crf section.. OK, now that i have put about 75 miles on my new bike and have the proper mods, let me finish this thread out by saying, i am absolutely in love with my new WR! for 1 thing my 2006 CRF has the 3.2 gal IMS tank, radiator braces and skid plate as well as HID headlights. otherwise stock. the WR is outfitted with the skid plate, brush guards, radiator braces, programmable tuner and the FMF exhaust pipe. so just basic protection gear and the obvious things to uncork the bike and get it running like it should. all i did to the bike was let some air out of the tires, and crank the compression and rebound down a few clicks on the front and rear shocks. first thing i noticed is i don't get as tired riding the WR. the ride is even better than my re-valved setup on my CRF the suspension is a dream, its so smooth and easy to ride. the weight of the bike feels 20 lbs lighter to me verses the CRF, with the new GYTR fmf exhaust i just installed i can now pull 3rd gear wheelies with minimal effort. the bike is worlds more quiet in the engine and transmission, even the exhaust is more quiet than the stock CRF pipe with the quiet insert removed. the throttle response is very controlled, my CRF felt like it wasn't as linear, like you twist 15% and you get15% at 50% you get 50% that much power. its the same all across the rev band coming over whoops i can hold the front tire in the air exactly how high i want it depending on how much throttle i give it. very precise! the WR is so much easier to ride wheelies with, i can literally grip the bike with my legs, lean back and in 3rd gear ride a wheelie for as long as i want. (keep in mind im at 7000 feet) my crf would do that in 2nd gear but not 3rd because the front end of the WR feels so much lighter than the CRF it could be in part due to my larger gas tank but even 1/2 full of fuel this bike feels lighter with a full tank. anyway, i am totally happy with my decision to buy this bike, i really cant find anything i don't like about it. i guess maybe it was time to upgrade. i suspect some of the short comings are due in part to the fact my CRF has about 140 hours on it, but only about 20 on the new piston and valves i had to replace. i have not heard of too many people with the yamaha having to replace valves like the CRF's so i hope mine stay in good condition. anyway if you guys are sick of waiting like i was, you wont be disappointed to ride the blue bike. i really liked my CRF and i still do, i had high hopes that the new WR would live up to those expectations and i am happy to report i think it has in every way.
