JUst becareful or be ware of the lite and prolite pistions they blow rigs and exsust skirts quick. Those pistions are great for racin but not really for an everyday rider.

 

wiseco prolite all the way.i have had a blaster and 250r with one of these pistons and i have never blown one i've only had to replace the rings about once every 12-18 months.it is a very good piston for riding or racing

 

Hey what ever floats your boat. All I'm sayin is or hell ya boy backed me up you blow the rings on them and you can only over size your rings so many times before you have to get it bored and not just honed out. I personal prefere the Pro-X pistion. I think it holds up better than any wisco.
