250cc & 300CC Custom Billet Heads
NOTE: This is NOT for the KTM version of the GAS GAS! This is for the engines and bikes that are NOT under the KTM manufacturing.
GAS GAS/REIJU 2-STROKE PERFORMANCE
NOTE: RK TEK IS 100% CONFIDENT IN THE PERFORMANCE OF THESE 250cc AND 300cc HEADS!
WE WILL OFFER A MONEY-BACK GUARANTEE
If the head does not offer a performance increase over your stock head, we will refund your money! NO RISK!
The RK Tek Head is UN-MATCHED in machining quality and performance!!
OUR heads WILL improve/widen the effective RPM Band GREATLY. TORQUE is increased at ALL RPM but our focus is, usually, directed to increase the lower and mid RPM torque. At no time will our heads give up top end performance or over-rev. We do NOT "Rob Peter to pay Paul"
The Stock 250 & 300 head are a VERY inefficient design and leave A LOT of Performance on the table.
We have developed a TRUE Performance Enhancer with this Custom Billet Head 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. Cooling is also increased. A cooler running engine will last longer and produce more power.
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.
Porting Packages are also available. This will wake up the engine even more!
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???
PLEASE stay tuned to this site for updates!
Head is available and custom made for ALL riding elevations and octane.. These heads are made for YOUR engine. Information is taken at the time of order and the chamber is designed for YOUR engine and application.
This head offers performance gains UNMATCHED by ANY other bolt on.. You will NOT be disappointed!
When you have a narrow power-band (stock head) the higher gears are not 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.
