I think the WR250 will not be enough bike for me. I would miss the power of the 426 too much and I know I would be kickin my butt. I am 6'2" and 200lbs and an intermediate rider. Long way to go to keep up with the pros I am down now to WR450(I love the idea of an e-start), the YZ450f( it would be like my 426 without the stupid kick starting drill) or a YZ250f. I don't race tracks very often. I am more into just recreationally ripping around on tracks. I will do the odd race now and then. I do like going into the woods and trails as well. I like the light weight of the yz450 but I think that I would have to put a 12oz flywheel weight on it and soften the suspension to make it half way rideable in the trials. The downfall is the gearing is a little tight. I was also thinking that you could WR time the YZ450 to make it a little milder for trail riding. Anyone know of someone who has done this to a YZ450?? The WR450 my only concern with this is the weight and the ability to ride it on motocross tracks. I love the idea of having a "LIGHT" and that MAGIC, WONDERFUL, GOD SEND of a button!!! Does anyone ride their WR450 on motocross tracks? And if you ride in the trails, are you finding the weight and power tiring you out? Also how TECHNICAL are the trials you ride? I usually have to deal with A LOT of rocks, deep mud (1' - 1.5' deep), and some BIG A$$ hill climbs. Also without making me search months of posts, what are some common problems with the WR450? and what are the free mods you have to do and what do they do. This bike would be the Canadian version. What does the wr450 actually weigh?? I have heard everything from 230 - 260?
