Torque-Line Heads by RK Tek (RKT)

We design our heads with a full knowledge of the engine's operating characteristics and, most importantly, the application and altitude at which the engine will be performing. We specialize in HIGH ALTITUDE applications but actually do more low elevation heads because there are more low elevation riders than high elevation riders.

We ONLY design TRUE hemispherical combustion chambers. With a true hemi -chamber, your engine can realize its maximum potential. Most other aftermarket heads are of the Flat-Top chamber design. This is mainly because they are more easily machined.

As of 2007, our combustion chamber design is patented. YES, the design is unique enough to be patented...

We can design a head that will fit the type of riding that your engine will be subjected to. For example, if you run a snowmobile at 9,000 feet and mainly boon dock and climb hills, we will design a head that will increase performance from initial start to peak torque RPM. If you mainly run lake races at 1,000 feet, we will design a head that will provide increased performance from peak torque to maximum over-rev.

We can also design a head for any octane requirement you need. If you have a particular application in mind, call us and we will make a custom chamber specifically for your engine. The combinations are endless! We can also re-shape your stock head's chamber. Note: Not all stock heads can be re-shaped to the "Hemi" design.

We are one of the only companies that will design and fabricate a head based on the application of the engine. Now, think about that, why would you want to buy a head that is "generalized" for all applications? Would you buy a compact car to be used as an off-road rally racer? OR would you buy a car that was designed for off-road racing?

RK Tek takes a different approach to 2 stroke engine building than most others. We use to get all "bogged down" with the "theories" that surround 2 stroke engines. Oh yes, we can speak theory with the best of them... What we shortly determined was that all those theories and formulas were based on engines from the 70's and 80's and do not apply to the modern day 2 stroke engine. The 2 strokes of the past were air-cooled and piston port induced. 2 stroke exhaust systems were in their early development and primitive compared to the exhaust systems of the later part of the 21st century. Well, the modern 2 stroke engine is water-cooled and reed valve inducted and has a very sophisticated exhaust system in place. A FAR cry from the engines the books were written about.

So, we developed some theories and formulas of our own that more closely mimic the modern 2 stroke engine and differ, sometimes greatly, from the books and SAE papers of the past.

We focus on internal engine flow and engine efficiency. We strive to increase the efficiency of EVERY function of the engine. By increasing efficiency, one increases performance.

MORE EFFICIENT = MORE PERFORMANCE!!!

It IS that simple!!

The more efficient engine also does not suffer form narrow engine power-bands. ALL our engines will have a very wide operating band and will not be finicky with elevation change.
