This was an easy one for a swinging arm bolt, its only 155mm long, M12. I’ve got a Hyabusa one in titanium coming up by contrast, its huge!
I’ve made a lot of parts for G45 and 7Rs, here are some titanium and 7075 alloy bolts. The 7075 alloy bolts are Surteck 650 coated.
Long engine mounting bolts like these are hard to get true, the deflection in the middle is considerable. Although its ‘only a bolt’ i can’t help getting them as accurate on the shank as possible, anything over 2 thou over the length is too much. So they take time to make, but are worth it when done. The fame inserts […]
Then after i’d finished all the alloy stuff i went back to titanium to make a font axle and suspensions bolts for an early Yamaha R1. The earlier models have an external thread whereas later models have the end of the spindle tapped and a bolt to match. The front spindle as standard had a tommy bar hole through and […]
Heres some 6082 alloy parts i’ve made for the head stem of either a triumph or NSU, not sure which as i’ve done work for both recently and he has so many i can’t keep track!
This is the last of the Montessa stuff i was making in the new year. I’m not sure what these hold on, they are bits from around a Montessa that could be lighter, and now they are!
This was a big job, 5 sets of axles for Montessa trials bikes, these are going to a trials team in Italy. They are all coated in Surteck 650 for corrosion protection. There are no nuts for the front spindle as it screws directly into the fork leg.
Here’s some titanium kickstarter bolts for Montessa’s, they are part of the same job as the rest of the Montessa parts i’m putting up here, there was a lot!
To go with the spindles I’ve done a titanium suspension bolt set for the Montessa. The OEM ones are pretty good on the tolerences so all i could do really was copy them.
Its Montessa time again! here’s another set of titanium axles going to H and D racing.
