I'm sorry I do not have any experience making the change in tyre size that you are contemplating.

I suggest you ask a dealer or knowledgeable person who owns the same type of motorcycle and has made that change. You are correct in checking with someone before making the change.

I'm sorry I could not give you a more complete response.

Ride Safe,
