OS Speed ​​.21GT Engine R21GT II SET - 1DT01

The powerful GT engine has evolved into the next generation! !!

The OSSPEED R21GT has inherited the smoothness and good fuel efficiency of the previous model, which was very well received in the European market, the home of GT cars.

This is a combo set:

  • Engine R21GT II
  • TB01 EFRA2042 (T-2060SC) resonance tube
  • MB01-70 (M2003SC) manifold

The feeling of performance in the medium and low speed ranges has been improved by reworking the crankshaft balancer. Additionally, the redesigned inner head improves no-load performance, and an O-ring on the inner head ensures less vibration and greater dust resistance. The outer head was made lighter and further developed into the OSSPEED R21GT II with great attention to detail.

The crankshaft is equipped with two tungsten counterweights. We optimized the mass balance by checking the detailed dimensions.

The inner head has been revised. Low and medium speed feel and idle performance have been improved. An O-ring is also used to reduce vibration and improve dust resistance.

The weight of the new outer head has been reduced compared to the previous model. The slats of the outer head were machined.

Equipped with 5 flush ports and 3 exhaust ports to meet IFMAR regulations.

Equipped with a double adjustable carburettor type 22E(B) GT. The new Venturi is 7.0MM(RED) AL2.
