I have been riding mx since spring (good dozen days on the track) with an 01 yz 125 love it and now clearing 70 to 80 feet table tops and "keeping up" with the regulars. Took a one hour course 1 month ago and ask my instructor if it would be a good idea to jump on my 01 yz426f (set as a supermoto right now). He said bad idea and that the 426 was a career ender and to keep it as a supermoto. Is that true? Cause I wanted my 426 to be a triple use bike. enduro, supermoto and mx. having 2 sets of tires and 2 sets of suspension.... And a parts wr400 Just ridding for thrils and a good work out.
