Here is one of the most efficient 80cc diameter Ø 49mm kits on the market for a 4t 50 PIAGGIO scooter engine.

This kit will allow you to go on a high ultra powerful and above all reliable engine. This very nervous kit could surprise more than one thanks to its breathtaking torque and the speed it can reach.

The high-end aluminum cylinder bored with a diameter of 49mm (actual 78.5cc). Its piston with high silicon content is very resistant and can therefore withstand the highest speeds. It is designed to give more compression and increase power, its steel segments are made to reduce friction as much as possible!

This cylinder is sold without the cylinder head because it is studied on the original cylinder head! This kit can bring out the power of 7hp, with the MALOSSI camshaft, a good exhaust like the TURBOKIT, a sport air filter, the MALOSSI variator and its belt ...

This kit can take 7.5 to 8hp! It could even wait for 8.5hp with a preparation of the cylinder head (conduits, polishing of the chamber, over-compression ...). Use only good oil and SP98!
It is sold complete, as you can see in the photo, with:
-Its pack seals
-Its piston
-Its Ø13mm axle
-Clips
-Segments, scraper
-2 rings Ø6,5mmx7,5mmx12mm
Please note this kit can only be assembled in the presence of the MALOSSI injection unit available below as a spare part.
