Maybe SPX or Wiseco. Stay away from Kimpex branded pistons as they will not hold up in these 8000+rpm triples. But in all honesty your best bet would be to go for the OEM if you can. They are the best. If not fitted exactly right Wisecos can be tempermental due to the fact that they are a forged piston, they are not for the back yard mechanic.
