KPX 250 with a set of Kenda Trakmaster 760s sounds like an excellent set up. The only thing that concerns me is dropping the bike
For me, the whole idea of a dirt bike is not worrying about falling over. KPX is too nice
The Templar bike are so inexpensive that I don't think twice about falling over, wiping out. It frees up my chance-taking urges when I am off-road. As long as I am not aiming for a tree or big rock, I can just go for it! And I have dumped the 5 speed many times. It is remarkably unscathed!
