Slovenian High-End exhaust manufacturer Roost introduced the Havoc Cylinder Kit is a 70cc 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 miniquads 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 an swap over.
