BMW Short sub-frame kit - /5 to / 7 Series & R45/65 1970-1984

BMW Short sub-frame kit - BMW /5 , /6, / 7 Series & R45/65 - 1970-1984

Our new BMW short sub-frame kit, designed to fit all the BMW R2v made between 1970 and 1984 (twin shocks), from the early /5 series (SWB & LWB) to the later /7 Series, encopassing the /6 and R45/65 Series.

Our sub-frame keeps its geometry very close to the original BMW sub-frame, allowing us to keep the same shock absorber lenght and to position our seat aligned with the BMW fuel tank lower edge for a smooth flowing line and stance. Its seat will lock and hinge like the original BMW seats, by fitting your lock mechanism in our frame.

Our BMW short sub-frame kit comprises:

  • FR short sub-frame
  • Upper shock absorbers mounting stainless steel fasteners
  • Offset RH lower shock mounting stud and s/s M10 nyloc nut + washer
  • Sub-frame mounting stainless steel fasteners
  • Fitted and adjusted rubber stops for the seat (bolt on)
  • FR Short seat – upholstered in pleated dark chocolate brown or black
  • Removable mid seat strap (bolt on)
  • FR stainless steel seat hinges (pair) + stainless steel fasteners
  • BMW OEM seat clocking spigot + conical rubber stop, s/s half + washer
    • The FlatRacer short sub-frame has been designed and developed with strenght and torsional rigidity in mind, a notorious weak point on the original BMW sub-frames. Our sub-frame is built with oval tubing reiforcements and features double wall tubing at its mounting points. Very strong mounts/spacers are welded in place to accept the original or replacement shock absorbers.

      It includes our newly developed short seat pre-fitted with s/s hinges and locking spigot, allowing to easily access the battery and tank mounts. The seat base is available in two versions (long or short to suit different BMW tanks) built to our usual standards in sturdy GRP (fibreglass) with typically 5-7+ mm thickness (will not rust or break).

£449.99

The seat incorporates a trimmed foam with the correct density and a choice of hot pressed (reducing the risk of water or humidity ingress) pleated seat covers, available in black or dark chocolate brown. The seat cover is supplied with a mid-strap which is removable.
