I can bounce off the RPM limiter at 62 (indicated) if conditions are perfect.

Stock motor with a pipe, 10.5 gm rollers, Simota filter, and an old skool Juice Box. :cheers:

I can hit 65 indicated flat ground no wind in a full tuck, 65+ with a tail wind, drafting, or downhill. Very happy with the TST vario and 10/12g weight combo. Still haven't hit the rev limiter with this set up but with stock vario I hit it at 62 like said above

got better top end until the state added extra mandates to what is mixed with the fuel. speed and mileage both dropped some after that.

Rider weight, tire inflation, wind, and incline all play a role in the speed this little monster can kick out. Put a <150 rider on slightly over inflated tires going down a slight incline with a fair tail wind and a warm engine on a totally stock bike except for the hook I bet he could top 70.

Honestly I don't really care about top end speed, I just love torque.

Post Re: Zuma 125 Top Speed
My 155cc Zuma hit 70 MPH indicated. . .
with an after-market pipe,
32mm throttle body,
stock ECM,
final drive gears upgraded from 8.5:1 to 10.5:1,
and the typical clutch-bell-variator-sliders upgrade.

If I remember correctly top speed was about 52 MPH when she was bone stock and bran-new.

In short I was very pleased with the results of dumping $1500 worth of gadgetry to gain 18 MPH. It made the bike "drivable" in fast moving cage traffic.
Yamaha did an excellent job when building those little bikes. Image

The poll should have been done in increments of 5 mph instead of 10
