Can anyone tell me if an inverted xr1200 twin disc front end would fit up to a 1986 fxr frame , and would the rake degree and length be similar to an original fxr front end ? Thanks.

 You be best checking harley part numbers s they keep using the same triples etc for a range of years and models. If they match up they fit. Sorry cant be more help but you never know what people know on his site.

Thanks for your reply that gives me somewhere to start cheers.

Subscribed.... Same bike and same theory here!

 I like your turbo setup,were you having trouble with the front end prior to your steering damper?

would you know anywhere that I could buy a gearbox ,inner and outer primary clutch and compensating sprocket to suit 86 fxr? Thanks.

 all harleys have a 1'' dia steering shaft from about  sporties from 1982 & big twin s from 1960 the sporty shaft  is a bit shorter than the big twin but i have used a spacer under the bottom bearing too fill up the difference  but best check on the XR dia 

 Thanks I'll check 

Re my fron tend...Yes the bike would get a wobble on fast sweepers (at about 100-120kph). Once the damper was fitted i can do the same sweeper at 160+ (not that I would ever try that...lol).

Just added a fork brace this week and man what a difference it makes. the entire fron end is now really tight and dead on! just need to get the suspension done now and I'm good to go.
