Question:
I would like to purchase one of your speedometers for my Triumph Bonneville America. I have been told by another owner that the following model works flawlessly on his bke:
Speedometer GP Style
SPEED/ODO
round
d=55
160 kmh (white fill
Product No.: BB551W10
I do not see this product available in the US, and I want a speedometer that reads MPH instead of KPH. What model would work for me?
Answer:
Hello Mat
Thanks for your interest in our products. Unfortunately, we do not carry this model of instrument in North America. On the other side, we do make a similar instrument in MPH with indicator lights. The parts number is BB641B34. This item is in stock and you can find it on our website at

Question 2:
Is there any functional difference between this model and the HD model BB551B40? Is the HD model adjustable for tire size to make it work for a different bike?
Answer 2:
Yes there is. The BB641B34 does have some indicator light while the BB551B40 do not have any. No the HD model only pick up the speed on the transmission. For this reason the BB551B40 can’t be adapt to other motorcycle. On the other side, the BB641B34 pick up the speed on the wheel and can be adapt to any motorcycle or tire size.
This might help with why the speed has not been reading accuratly on some of the Koso speedometers.
