i think it should do alrite...i race mx with my blaster in C class and can compete for top 5 every race. mine has got a couple more things than yours does, except for the boost bottle. u should fair pretty well in a mx race. but word to the wise.....dont take your blaster to a big track with a lot of uphills and strait aways, its impossible to hang with the 4 bangers on the flats. i go to some of those races for the fun of it but i can be a top runner in a supercross setup track.
