OK, I am getting back into dirt bikes after a 6 year break. I already have a bike for the street (06'Triumph 675) and its wonderful. But on some recent rides, I have found that I miss the satisfaction that dirtbikes gave me, and I want to get back into riding dirt. BUT there is no place to ride around here, everything has gotten posted over the past few years, so I will be converting this bike to super-moto, and maybe converting it back every now and then to do some trail riding/joy riding. I have narrowed my selection down to two bikes, the XR650r and the WR450F. I can get the 650 $5200 plus tags, and the WR $6200 plus tags... I would much rather have the yamaha though because im a bit biased to yamaha, and I love the fact that it has the cool speedo/computer. I am 6'1'' 275 (I also play college football, that explains the weight, and im not fatty just for the record, very athletic for my size) and I was wondering how the xr and wr compared in size and power? Which one would be better suited for a larger rider? How do these bikes compare heads up? Any problems converting these to supermoto (besides getting registration for the street, I already know its a pain in the dick)?Any feedback is greatly appritiated, thanks in advance.
