Malossi 70cc "MHR Team Cross" Cylinder Kit MBK Nitro / Aerox (for 85mm connecting rod + 12mm piston pin), one of the most powerful 70cc racing kits on the market.
The cylinder has 7 transfer ports and a bridged exhaust port, it comes with a single-ring piston (12mm pin) and a high-compression modular cylinder head.
The key difference with the "MHR Team 2" is in piston design: with the "Cross" the piston pin was set off to allow for a 85mm connecting rod without the need for a 5mm cylinder spacer.
This kit can reach more than 20hp out of the box, but only with the right set-up (Hyper Racing exhaust, racing ignition, 28mm carburetor etc.). The power band is narrowed down a bit, by approx. 1,000 rpm, this means leass hp, but much better torque.
For even more power and performance you can ask our MXS Custom team to prepare the cylinder for you, just send an email to [email protected] indicating the article number of the cylinder in question.
Note: You'll have to mill the crankcase to make room for the cylinder base (see manual for detailed instructions). Can only be used with 12mm piston pin and 85mm connecting rod.
As with all aluminium cylinders, you'll have to adjust squish clearance for maximum power and reliability.
