70cc 45mm Athena kit for Sachs 504 and 505 engines. Comes with Sachs style cylinder/head combo, piston, rings, wrist pin and clips.

This kit is generally viewed as a more "mild" option as far as Sachs kits go - it's a substantial power bump from stock, but not enough to destroy your clutches like the 80cc reed kit. This guy is a perfect choice for your everyday rider. That said, it is definitely a good idea to upgrade your clutch friction discs to cope with the additional power. You can grab those here.

This kit will work with either Sachs crank stroke length (42mm or 4mm stroke), though it makes substantially more power when paired with a long-stroke Sachs crank like the TOP Racing Evolution crank.

Also be sure to grab a new decomp valve if you need it!
