Tough as nails

Comments On Mar 16, 2014:Have 7 years on the Wiseco that's in the bike now. Only changing due to new crank installation. I guess 'reliable' is the word I'd use.

Warning

Comments On Feb 07, 2014:These pistons are forged aluminum and expand at a different rate then your cast cylinder. We followed all directions and even had a local machine shop drill the oil holes in the piston to make sure exact measurement and drill sizes were used. Warm the bike all the way up every ride out before setting out on a good ride. The piston will expand faster then the cylinder if you don't and cause and cold sieze condition. Very costly mistake. Parts are good as long as you want to be extremely careful about warming up engine every ride out.

Don't go cheap for engine compenents. Go Wiseco

Comments On Jan 03, 2014:Wiseco is almost a garunteed perfect product. Not quite as good as OEM but a lot better than most of the competition. I always get a full 35 hours on my race bike (YZ125) off these top ends.
