Replacement swing arm bolt

Post  JohnW on Sun 3 May - 20:32

The swing arm bolt on a T80/T50 is M12 x 185mm long with 25mm thread length. These appear to now be unavailable new but I have found a source on eBay for a bolt that should do the job. (Only £6.75 for a pack of 4) Its M12 x 180mm (slightly shorter but this should not be a problem) High Tensile steel available from  http://www.ebay.co.uk/itm/M12-x-180mm-HTB-HIGH-TENSILE-ZINC-PLATED-HEX-HEAD-BOLT-QTY-4-/350492476518

If anyone buys one lets have a feed back please.

Hi, I tried a set of these as my bolt was seized solid and had to be drilled/cut out. Unfortunately they are not suitable as the thread pitch is incorrect. The bolt should have a 1.2mm pitch (fine thread) and these are 1.7 mm . For info I got one suitable for a pit bike, modified it slightly as it was to long but otherwise works a treat!
