The OEM 300 heads do not employ a good functioning squish band design. This lack of good squish "action" is why you can have inconsistencies and run ability issues (ie flat/dead spots, temperature sensitivity etc. etc.).

RK-TEK's specific (Patented) design keeps the compression ratio in check and allows for well functioning squish band. This ,GREATLY, improves torque output and reduces the onset of detonation. In short, your engine will perform like it should with a very SMOOTH and LINEAR torque delivery. Wheel spin is REDUCED so better traction is the result.

Also you will be much less tired as a result of not having to use as much energy to "control" your bike. The smooth and linear power delivery takes this burden off of you. You will not find a better mod for your engine and yourself!

Your bike does NOT require ANY ECU changes in order to work with our Heads. We have been working with 2 Stroke Engines for decades!! We have the experience to make a head that offers SIGNIFICANT performance enhancements with out the need for any ECU changes.

 

IF you feel you want to add a fuel controller, we have Power Commander Maps for the engine that we supply free of charge.

 

*PLEASE.. do not get taken in by this internet "hype" regarding the need for ECU changes.

It simply is not true! Your engine will run just fine with the RK Tek Head.

 

When you have a narrow power-band (stock head) the higher gears are not very usable because the engine will not supply the needed torque at the lower RPM. So, you are forced to ride in the lower gears in order to maintain any torque.

After the head install, the torque is produced at a MUCH lower RPM than before. This allows for 1-2 gears HIGHER when in the slow and technical or the heavy loaded hill pulls.

The higher gear running allows for faster overall speeds and less fatigue on the riders part because the rider does not have to "work" as hard to keep traction.

Almost all will find they are faster and in more control when running the higher gears. With this confidence increases as well.

Great way to get a huge performance increase at a cheaper cost!

 

The Stock 300 head is a VERY inefficient design and leaves a lot of Performance on the table.

We have developed a TRUE Performance Enhancer with this Custom Billet Head designed specifically for woods 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, without noticeable drop of between torque ranges.

 

This head is unequalled in its performance. Cooling is also increased. A cooler running engine will last longer and produce more power.

Remapping to force more fuel in isn't the correct way to make power, using more fuel and stressing out the fuel components. Correctly utilising the mixture available is how it should be done.

 

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.

ANOTHER HUGE bonus with the addition of the head is improved fuel economy! This is ,usually, the result of the higher gear running.

Most find they can run an extra 10-20 miles further on the same amount of fuel!! Now who doesn't need that???

 

This head offers performance gains UNMATCHED by ANY other bolt on..

You will NOT be disappointed!

 

Each custom head is machined especially for UK fuel octane rating (E10/SUPER) and altitude here in UK
