The thing about motorcycle speedometer is..... it is not accurate at all. It is only accurate to about 60-80 and then the error becomes enormous.

For example the infamous Yamaha LC135. The owners would surely become happy cos on stock the bike can go 150km/h... as indicated by the meter. Well how true is it? I follow my fren at 150km/h, my bike only shows 120, a difference of 30km/h and my bike's meter is not even accurate too; my bike 100km/h, Suzuki GSX750R 91km/h.

Btw, my bike can go 155km/h max as on meter.

Last time I ride a suzuki fx110, fuhhhhh out meter (over 150). Then go test with a friend rise at the side, 100-110 only hehheh

And then about 7 years ago, I rode my dad's Honda CD175 with a friend that's riding 125z with tayar sotong. he told me he will ride at 90km/h. I follow him all the way to another nearby town, my meter is reading 40mph (about 65km/h). I asked him why the hell ride so slow, he told me he's riding 90km/h lol. Tayar sotong for the win (reduces the radius of the wheel to make the meter reads faster haha)
