Kit 183cc ATHENA Ø63mm, cylinder / piston for YAMAHA N-MAX, MBK OCITO 125 from 2015 to 2016

ATHENA RACING BIG BORE 183cc kit for YAMAHA N MAX and MBK OCITO 125 scooter with 4T 125cc injection.

This kit is composed of a reinforced cylinder in nicasil treated aluminum in diameter 63mm, which increases the displacement to 183cc of torque and power with the original crankshaft of 58.7mm stroke!

The VERTEX piston offers a new, more efficient compression ratio of 11.4: 1 against the original 11.2: 1, so the torque curve increases quite a bit too!

The pure gain (bench tested) is enormous, more than 20% of power and torque gained! The power goes from around 10.90 to 12.60hp real!

We recommend this kit with a sport air filter, a sport variator and a sport exhaust line without catalyst, a cold irridium racing spark plug is always better if you have all the equipment, so switch to a CR8EIX! The kit comes with the box for easy connection, gaskets, segments, axle, clips, gaskets, very complete instructions ... Only use SP98!
