Wankel Rotary engines have been around for many years in some form or another as with all engines there are positives and negatives, BUT with many advances in technology the basic design gets pushed to new limits, costs come down and a new market niche is found. In this case karting. In the past kart engines have proven popular paramotor engines, small, light and fast, but with high service rates.
