155/164cc EXTREME results and WRRP exhaust system

Finally got dyno results for our 164cc kit, somepoint in the next month or so we will do a video of it accelerating.
So nearly 17BHP at the wheels, this is a huge amount of power for a tiny 58.5mm piston.



Also on the video is the new WRRP exhaust system.
We are very confident that this exhaust makes more power than any other pipe on the market for stock,155 and 164cc bikes.
Not only that but all within a reasonable sound level, you can ride about and nobody can tell you have a tuned bike!.
