Stan S recently very kindly donated a pair of forks for a project bike (thanks again Greg) He wasn't 100% sure he had the right fork tubes or springs though. The sliders are the black painted "finned" model not leading axle and obviously Betor with the Bultaco logo cast in situ. I believe they are supposed to deliver 200 mm of travel. My questions are how long should the fork tubes be (they measure 570mm) and what length should the springs be (the set I have measure 450mm) Any help much appreciated. Thanks Jerry

Jerry i have a set of these(finned betors) which i thought were off a 76'ish 125 pursang ,their going on my mk-5 project ,i'll check them out see if their the same later this arvo -cheers

Thanks Huski any feedback much appreciated. J

I believe those forks came on the Mk9 125 of 76.

Hey jerry ! springs measure 430mm ,the assembled forks are 790 from axle centre to top of tubes and they have around 200 travel, iam not sure of the history of mine but as JC say's mk9 125 , not sure if frontiera's were the same dimensions ? cheers

Thanks Huski. I will hit the man cave with tape in hand tomorrow. Let you know how I go. If your interested the Pomeroy replica build has regathered momentum after some family illness. Im also going to run it in some Vinduros with a Frontera tank, forks, Preston Petty headlight and tailight as well as different swingarm and LTR. Cheers Jerry

They also came on M180 Mk10 250 fronteras, circa 77.
190mm/7.5" travel

No worries jerry ! Always good to see a bully brought back , especialy a early/mid 70's Pursang, and even better something outside the square ( eg hotrod or replica) - keep us all informed on how it's goin' . cheers
