Frequently Asked Questions
Will this fit my 1992 ST1100?
Not directly. The 1990-1995 models used a 28A oil-cooled alternator. While this 40A unit is a popular upgrade, fitting it to a pre-1996 bike requires changing the mounting bracket and other components.
Is this air cooled?
Yes, this is the air-cooled 40 Amp version found on the later Pan European models, known for being more reliable than the earlier oil-cooled units.
Does it come with the cush drive rubbers?
No, this listing is for the alternator unit only. You should inspect your existing cush drive dampeners and replace them if worn to ensure smooth operation.
Note: Please verify your motorcycle model year before purchasing.
