Re: Mechanical speedometer
I bought 6 of the plastic speedometers when NCW had a closeout sale on them for $6.00. Two of them have over 600 miles on them, and two went on bikes I sold. As far as I know they are still working. If you search around you can find The Stewart Warners for around $80.00. I have one i'm not to impressed with it for that kind of money.
I generally buy the $10 digitals. If they are a couple m.p.h. off so what. I am sure I am not breaking any speed limits with these Chinese motors.
