TKR1712X BLOK 21bM .21 Competition Buggy Engine (Grey Head)

Product Description

NON BROKEN IN ENGINE

Intended for buggies but also well suited for truggies, the BLOK 21bM engine provides the smooth, linear power band and excellent fuel mileage required at the highest levels of competition.  The bottom-end starts out incredibly smooth, then pulls through the mid and high end to give you the extra grunt to hit that short take-off and additional acceleration for the straightaway. Features include a long-stroke piston and sleeve design, DLC coated silicone-filled crankshaft, laser-etched low profile cooling head, blue 6.0 and 6.5mm venturi, plus all components are interchangeable with the popular 21aP. It comes paired with the 21J carburetor which is widely regarded to be the gold standard due to its tunability and consistency over wide-ranging temperatures and humidity.
