When did the RK Tek big bore come out?
NOTE: RK Tek was the FIRST to develop this 860cc big bore. It was developed in December of 2006 (remember the 800R was introduced in the 2007 Summit model only). Since its introduction, MANY other shops have also developed an 860 for this power-plant.
How much power does a RK Tek 860r have?
The new 860R from RK Tek is rated at 180HP on 91 octane fuel with the stock exhaust system. Peak power is accomplished at 8300 rpm. The torque curve is extremely broad and linear which allows for VERY easy clutch tuning. Fuel economy is INCREASED over the stock 800R due to the more efficient engine.
When did RK Tek get the Rotax 800R?
RK Tek spent a better part of the 2008 Season developing a performance package for the new Rotax 800R (ETEC is the SAME ENGINE) Engine. NOTE: This 860R kit was designed and built FIRST by RK Tek in 2007! It is the “Original” It OVER 9 FULL seasons of testing associated with it.
Are there any 860cc big bore kits available?
While there, now, exists many 860cc Big Bore kits not all are created equal. Think about Pizza, You can get a Ham and Sausage Pizza from 1000’s of Pizza Parlors and on the outside they will all look very similar.. BUT…once you bite into them, they will, most certainly, not taste the same.
