Specialist one off and prototype machining

Beta Enduro Bikes

Rear Brake Clevis

The standard rear brake clevis has almost 3/4mm play in pin.  This results in about 20mm of play and the pedal making it particulary difficult to use the rear brake on a steep downhill section.   

These are machined from aluminium alloy with a stainless stell pin to exacting standards and tolerances elimating all of this play.

£21 for the complete kit which includes washer and split pin.

These will fit all the 2 stroke and 4 stroke models from 2016 up to the the current year

Cup Washers

There are five on your bike:

  • One on the front mudguard (used to hold the brace in place)
  • Two on the chain slider
  • Two on the rear mudflap
  • There is also one on the silly filmsy chain guide but most people take this off (before it breaks off) so I recommend you need only 5.

These are made from 6082 alluminum alloy and replace the pressed steel ones that corrode and make your bike look ugly.

These are supplied with stainless steel washers to prevent electric corrosion between the ally washer and your steel bolts.

£2.00 each ( includes a stainless steel washer)

The red rockets were typically the 250cc 1978 - 1980 models.  If you have a different year these may not fit, but do not dispar, I will probably be able to make them to suit your year bike.   Please get in touch to discuss in detail.

Rear Brake pin
