This week we are taking a look at a high-performance RK Tek Billet Head. They make this head for KTM, Husqvarna, and Beta 250 and 300 two-strokes. The head comes in orange, gold, and black.
RK Tek has been in the two-stroke game for more than 40 years and has a mountain of experience to back them up. Based in Preston, Idaho, RK Tek actually does most of its work on snowmobiles since most still have two-stroke powerplants. Yet, as avid dirt riders as well, they’ve turned their machining powers to their dirt steads.
According to RK Tek their billet head is not only designed to increase power, but also is specifically shaped to widen the meat of the power for off-road, single-track riding. They focused on lessening the hit and even make the power feel more four-stroke like without adding two more strokes to the bike. According to RK Tek’s testing, the head also increases fuel mileage and the shell is machined from 7075, which helps with cooling, as well.
On paper, this sounds like a great addition to a two-stroke that sees a lot of rooty, rocky, nasty terrain and for the rider who still loves his or her pre-mix but wants a smoother, easier to ride off-road bike. Hopefully we will get a one of the applicable two-strokes in our test fleet soon so we can put this head to the test.
