Santa Cruz 6R4 HT2

05 October 2021

Group B Rally Inspired

The new Autosport mag arrives in the post for my Dad. I wait patiently for him to hand over the free poster and I run excitedly to my room to add it to my wall of 90s race cars.

One such event gifted me a “double pager” of the eye-melting MG Metro 6R4.

Rothmans 6 R4

This simple memory of a poster on a bedroom wall inspired me to build a bike in the spirit of the MG GroupB beast (without the 3L Williams engine and without the 410bhp and without a roll cage etc but we’re splitting hairs).

The brief was simple, build something:

  • With 6R4 livery

  • That was as light as possible

  • With mixed wheel sizes

  • Custom Ohlins suspension

All in the detail

This wasn't as straight forward as bolting a bike together. There were some extra mods that we needed to make this bike exceptional.

  • Frame Modifications: Cascade link mullet conversion
  • Full Ohlins suspension custom tuning
  • Rear Axle: Burgtec Santa Cruz 168.5mm Rear Axle - T 12mm / TP 1.0mm Race Red
  • Linkage bolts: UNITE Santa Cruz Linkage Bolts Red Santa Cruz
  • Shock Bolts: Burgtec Ti
  • Tubeless Valves: Peaty's Mix kit
  • Frame plugs: AXS frame plugs
