I pulled 43.75mph @ 6500rpm on my 3 speed shifter bike...

Engine is still new and stock.

I still have to port the barrel, fit an expansion chamber and install a 19mm Dellorto

Should pull another few MPH then!

lol you guys are funny. Every motor bike I see, there is so much improvement to be made for better speed.

1) You're riding knobbie tires. Are you serious? That's eating 10% of your speed right there.

2) How many of you wear tight, aerodynamic clothing? TONS of speed to gain there.

3) Riding position. These bikes have you sitting upright. You might as well be pulling a parachute.


Here's some food for thought. It only takes 500watts for the average aerodynamic road cyclist to hold 30mph on flat ground. (Not that that's easy to pedal!!)

800watts for 40mph, and so on. Although to get to 40, a rider would need to hold over 1000watts for 12-15+ seconds.

Point is, get slick tires, get tight aero clothing, and tuck yourself IN and LOW when going for speed!

Experiment with gear ratios too.

My gps and my calibrated bike speedometer, read the same, and when I pass the radar it reads the same, when I put the gps in my truck car its reads the same soo must be ok.

The GPS will be the most accurate.
