Description
The Stock 150 is a very inefficient design and leaves a lot of Performance on the table. RK Tek has developed a true performance enhancer with this custom billet head insert designed specifically for mountains and single/dual track riding. This head will widen the engine’s effective power-band considerably and allow for a much more linear power delivery. This head is unequaled in its performance. Testing has shown, in many cases, this head allows for the hill to be pulled in the next higher gear . What you would normally pull in 2nd gear you can now pull in 3rd gear.
