Hey guys,

looking at putting a higher compression piston in my 09 250X and I found this company called Wossner Piston. They offer a few different classes of piston but they offer one that supposedly increases the CR to 13.5:1 which is a dramatic increase but could possibly compromise the bottom end or other engine components. Has anyone had any experience with this company or with increased compression in their bike?

make sure you properly tune the bike to run at the new compression

There are diminishing gains from a compression increase & you would no longer be able to run pump gas if you went that high.

You'll see much more improvement from increasing the displacement. The TR 280 kit or the Athena kit would yield a much bigger increase for the same amount of effort & not require you to buy race gas.

At the most, you might see 8% with race gas. With a big bore, tuning & pump gas you could easily see upwards of 20%
