For a sporty driving experience on the road, we suggest getting the Stage6 50cc Cast Iron "StreetRace" MBK Booster / Stunt (Minarelli vertical) for a very good price!

The kit includes:
- 50cc Cast Iron Cylinder, d=40mm, with 5 transfer ports and a simple oval exhaust port
- Two-Ring Piston, 10mm pin, with piston rings and circlips
- High-Compression Cylinder Head, aluminium
- Base and Head Gaskets

With 50cc displacement, this cylinder kit is of course street-legal. With lots of power and lots of torque, it is a great choice for riders looking for an increase in performance for everyday use.

To exploit the full potential of this kit, we recommend combining it with a 17.5mm carburetor and a sports exhaust; with this set-up, it can easily reach 6 or 7hp. We recommend a Stage6 Pro Replica or a Yasuni Z.

Stage6 50cc Cast Iron "StreetRace" MBK Booster / Stunt (Minarelli vertical) is street-legal/CE homologation.
