I have owned this bike for 2 years now and love it as much as the day I bought it. I can ride with my son on his crf80 or rip it up with any other 450 out there. It may not be the lightest or the newest but it does everything I ask of it every time I need it to.

The WR 450 is a fantastic machine. In stock trim it is a bit on the gutless side, but this is due to all the junk the factory put on it to get it to pass EPA emmisions. The first things this bike needs is: - Remove the exhaust baffel - Swap the WR throttle stop for the YZ (the WR only lets you twist the throttle 1/2 way - Open the air box up and trim the snorkel - Clip the grey wire on the CDI to match it to the YZ ingition timing This will transform the bike into the ultimate offroad machine. For added punch, swap out the WR cam for the YZ cam - the power is increased and you now have a YZ450F with electric start, a larger tank, kickstand, lights, heavier flywheel, and a Wide Ratio (hence WR)tranny. The Wide Ratio tranny is exceptional off-road, but does require more work on the track. Thats right, this bike is just as fun on a track as it is on the trail. As mentioned, this bike does have a lot of extras over a YZ450F, but at a price - weight. This bike weighs 25 lbs more than a YZ, but the down side is where it carries the weight......its up high. The battery is right under the seat, the larger fuel tank is obviously up high, as is the heavier exhaust can. What does this mean? It makes the bike top heavy which wears you out on the track. On the trail its not as noticable, but you can tell its there. I have seen many others swap their exhaust, fuel tanks, and seats for those of the YZ and they felt it was a big improvment. I myself have not had the chance to do this yet. I rated the handling a \"4\" because of this.....it is too heavy to be a 5, it should be a 3 on handling, but the fact that it can be changed with minor mods merits a slightly higher rating than a 3. Reliability is fantastic. I have over 1000 miles on mine. My valves are still in spec and it fires up very easily. The forks at shock are top notch, but only after having them professionally tuned. I am a bigger guy (6\'3\" 285 lbs)and the stock suspension was just not upto the task of handling the abuse I dish out. I installed much stiffer springs front and rear as well as had them revalved for my riding style and added additional subtanks, all I can say now is WOW! Overall, this bike is setup to be a great trail bike stock, with the minor mods posted at the top of this review (which are free sans the YZ throtle stop), it is a very competative desert racer, and with a suspension tuning and minor ergo mods (seat/tank) this can even be a fun MX machine. This bike is bar far, the most versatile machine I have ever owned. Trail ride it on Saturday, MX race it on Sunday, and with a few modifications (check you local DMV) ride it to work on Monday! I give this machine 2 thumbs up!
