MK1 tuning kit for Weihrauch HW50

Tuning kit MK1 HW50, HW50S, HW57, HW99 with original WEIHRAUCH spring

The kit was developed in collaboration with the English author and tuner Lyndon Lewington of ARC Tuning. It is based on the well-known and proven V-Mach tuning kit by Steve Pope. All components are matched to each other using an original Weihrauch piston spring.

Installing the tuning kit is straightforward and takes only a few minutes.

We now use the significantly higher quality V-Mach piston springs made of Japanese spring steel, which is why the remaining stock of this kit with the original Weihrauch spring is being sold off at a greatly reduced price.
