This is a rare brand new Harley-Davidson tachometer that my Dad has had in storage for years.He bought it new and never installed it.It is part #92051-81A.It is brand new in the original box.The info I could find said it fits Sportsters 1974-1980,and it shoud fit some FX models of the same era,but I am not sure.Again this is a Harley-Davidson tach,not aftermarket.Thanks. $100.00 OBO shipped.
