I realize that Bill, but Joe blogs is just your average racer. Not an expert.
Availability to the public as a whole is the issue.
I am not questioning Dave's integrity or his bike, it is just that he is the only one that I know of with a RH
My point is : It being a RH ( works, semi works, limited edition, only available to a selected few, whatever ) would have Pre Production parts fitted to differentiate it from a TM. Exactly the same as Anthony Gunter had in 1977 when he had a Suzuki alloy arm fitted to his 370. I understand the RH may need to be lowered to comply with Pre 75 rules . Both bikes were limited edition works/ semi works bikes available only to a select few.
If the RH is legal surely the 77 alloy arm has to be deemed legal as well.
