Slovenian High-End exhaust manufacturer Roost introduced the Havoc Cylinder Kit is a 2FAST70cc cylinder for Minarelli style engines in late 2015, it proved to be a race winner. Now the New Generation 2 Havoc cylinder is being released for the 2017 season and with improved performance, it is expected to dominate may race tracks.
It features a new water-cooled exhaust outlet design that’s new in the scooter-Miniquad scene and promises huge hp out of the box. Fits most liquid-cooled mini quads such as DRR and Apex.
Kit includes a custom handbuilt "UPDATED" Roost exhaust tuned specifically for this cylinder updated version. This cylinder requires a 39.2 stroke crankshaft with 85mm rod, same as R/t 70 and 2Fast 70 so makes for a swap over.
Our testing has shown that this kit can make more HP and Torque at less rpm than other leading brands.
