"I've been testing this barrel on my 23 300 TPI and alongside the TSP map this is a game changer! Significant gains to the bottom end and smoothness of your TPI" Tom @ x-duro-worx
After six years of racing the KTM TPI platform engine at the highest level of Hard enduro including testing with the world’s best riders: (Jarivs, Kabakchiev, Goggia, Hoare, Brightmore etc) we have developed the Rutherford Racing Hard Enduro cylinder. this has modified induction and exhaust port timing so that the motor starts producing power much earlier and much smoother. combine this the other Hard Enduro Set up bundle to get the best possible setup for your TPI if you want strong controllable bottom end power, similar to how the TBI is but with grunt.
We have ridden the below Husqvarna factory TPI bike in 2021 which uses very similar port timing to our cylinder.
You will want a ‘A’ size piston.
Fitment:
KTM 300 XC/EXC 18 to 23
Husqvarna TE/TX 300 18 to 23
GasGas EC/EX 300 21-23
2023 bikes will require these pv retainers
