Tankbag Posted January 23, 2019 Share Posted January 23, 2019 Good TMBF bike nuts, I'm changing the alloy rear sub frame to a steel one on my gen1 Hayabusa. It's not in the Haynes manual, does anyone have any tips please. TIA Quote Link to comment Share on other sites More sharing options...

Fozzie Posted January 23, 2019 Share Posted January 23, 2019 Take a picture of the current assembly. Undo everything attached to the rear subframe, even transferring it to the new one while doing so if convienientRemove the subframe and put the new one in and put everything back on the new one where it was on the old.That's all there really is to it (If it's like the 2 or 3 I've done).

fastbob Posted January 23, 2019 Share Posted January 23, 2019 May I ask why you would want to do this modification ? Is the ally one weak or something ? Quote Link to comment Share on other sites More sharing options...
Tankbag Posted January 23, 2019 Author Share Posted January 23, 2019 May I ask why you would want to do this modification ? Is the ally one weak or something ? Yes Fastbob the ally one was changed for steel from 03 onwards & there was a recall due to some of the ally ones cracking due to the extra leverage from a pillion / luggage / both. I've got a nice trip to Colditz Castle planned & I don't want to risk it with my new luggage. I've sourced a steel sub for just 60 quid Quote Link to comment Share on other sites More sharing options...

Stu Posted January 23, 2019 Share Posted January 23, 2019 It's an easy job to doIf you're unsure then take pics The hardest part is usually removing the undertray as the bolts are usually in all the elements and they can be a tight fit Most of the time you can get away with leaving everything attached to the undertray and just dropping it down on to the tyre Quote Link to comment Share on other sites More sharing options...
Tankbag Posted January 23, 2019 Author Share Posted January 23, 2019 Thanks [mention]Stu[/mention] I'm not gifted spannerwise but I'll muddle through, it's worth it if I avoid a large cracking sound behind me then the rear of the bike sitting on the tyre miles & miles from home Quote Link to comment Share on other sites More sharing options...

Chrissb6 Posted January 23, 2019 Share Posted January 23, 2019 Was'nt there a recall over this issue? I know it all came to light when the Busa Gen 1 went from an all-out superbike to a sports cruiser and the luggage went on. Quote Link to comment Share on other sites More sharing options...

There was a recall Chrissb6 but either the original owner of my bike didn't take it back or it wasn't available in the UK or something Quote Link to comment Share on other sites More sharing options...
