MXS Cylinder Kit "GP90" stroke=45mm Yamaha Aerox / MBK Nitro

Maxiscoot and MXS Racing proudly present the result of many years of development: the MXS 90cc Cylinder Kit GP2 (45mm stroke) MBK Nitro / Aerox! And, as a matter of course, to be had for a very good price!

The MXS 90cc Cylinder Kit GP2 (45mm stroke) has an original patented design and includes a 90cc cylinder (d=50mm / stroke=45mm / conrod 90mm => 88cc). These cylinder kits were developed for "Hyper Racing" and are, accordingly, extremely powerful!

Among the new developments for version GP2 - differently shaped exhaust ports and a newly designed combustion chamber for the cylinder head to boost the performance of the MXS cylinder kit even more. In combination with the right components, but without any additional modification, this kit can reach between 26 and 28hp. The special transfer port design will give you phenomenal torque of 18N·m - even in the low rpm range!

The MXS GP2 90cc cylinder is very powerful at take-off, has impressive acceleration and top speed. Thanks to well-thought-out design and the use of top quality materials this kit is also top-of-the line regarding reliability and durability (manufactured in Europe).

The kit has to be combined with the MXS crankshaft GP 45mm stroke (90mm conrod), the MXS exhaust GP90, a 30mm carburetor (38mm would be ideal), a racing clutch, an oversize variator, a "long" transmission and a digital inner rotor ignition (Stage6 R/T).

Note:

• You'll have to mill in the front of your crankcase a little to make room for the connecting rod and the cylinder base (manual included)
• It is possible to get even more power out of this kit by using a racing combustion chamber for the cylinder head that is sold separately (can only be run with high-octane fuel); the kit can now easily reach 28 / 29hp.
