Surprisingly accurate speedo on my 98 RSTC

[Lug Nut]

Used GPS app on phone tonight....0-40 mph speedo is 1 mph shy....40-80 mph it is 2 mph shy. My Roadstar and RSV were much further off...like 5-8 mph shy. Thought it interesting that my oldest highest mileage bike reads the most accurate.

My 07 TD is exactly the same calibration as yours. Go figure. I don't get as to why Yamaha purposely calibrates the speedo's as such. No rhyme or reason to me.

Wondering if a P.O. put a speedo healer on your scoots. Teeny circuit board, plugs right in, let's you dial in correction.

Don't think I've heard on any metric factory scoots with accurate speedos from factory...
