Since 2016 HP has offered an in house 270 kit for the KTM group of bikes. It's a strong performer and outshines the other kit on the market by a good bit. We briefly stopped selling our kit when the big manufacturer kit hit the market because of their tremendous advantage in pricing, but after testing back to back, I decided to start making the kits again due to our large performance advantage. It's my opinion people don't just want a bike that IS 270cc, but a bike that RUNS like it's 270cc. We've attached a short youtube of everything you need to know about the base level 270 kit. It's available in our store and is in our opinion the single best budget mod you can do for a 250 ktm, gas gas or husky.
Our Kit uses a custom designed, CP made piston, with a DLC coated pin, anti friction skirt coating, low tension oil ring and optimized, lightened shape that minimizes any excess material. We have 2 versions, but are mostly selling the 15:1 piston, which CAN run on pump gas. This kit works best with a properly tuned EC, which can be clearly seen in our youtube video. If you own a bike 21 and newer bike, you can NOT reflash the OEM ecu. We are working towards ideas around this - but for now an aftermarket CDI or fuel piggy back controller is needed. These bikes flat out RIP and are about as much fun as you can have on 2 wheels. You can couple our custom ground camshafts and valve springs for even more power.
I've also attached a chart from a different bike and test (using stp correction rather than what we publish now days of SAE which "reads lower") of a perfectly tuned 270 kit from the other offering on the market that had a vortex ecu and dyno tuning vs our kit with same ecu and different tunign to match ours. The difference was quite large in this case - but in other testing we usually see a 2 hp difference. It's a little bit baffling - as we really like all the parts of the other kit, but it just hasn't performed as well for us.
