Whizzer speed?

[darwin]

How fast do those go? From what I read they're 125cc. That size scooter should top out in the mid 50s.

I've often wondered myself, I'm like you if it's a 125cc it will probably scare you.

2 or 4 stroke? I haven't seen a 2t 125cc engine on ebay for sale

Whizzer engines are flat-head 138cc, in stock trim they have a little over 2.5HP and 4.5 lb/ft of torque. They aren't powerhouses for their displacement, having quite low compression for a 4-stroke and an intake restrictor, but they are under-stressed. Easy 40MPH out of the box, with more available with a few mods. They are prone to running hot if beat on, like most other flatheads.

I'd just go for a 4 speed Lifan 125cc then. I beive that's around 7-8 HP. Not so easy to install, since it's not a kit, and doesn't include the parts (Throttle, sprocket, chain, mount)

Not my Death Trap - Just a picture I found on line to show the OHV kit installed on a Whizzer.
Guys put OHV kits on New Gen Whizzers too
Those wheels are 11 or 12 gauge spokes I think their fine.
Who needs Brakes? That Drum Brake looks OK
Talk about Crazy, Back in the 20s the BTR racers had No Brakes and went over 100 MPH
No BS some people ride Death Traps
Picture - 1912 Indian 1,000cc BTR went 95 MPH No Brakes and Crappy forks.
Picture 1913 Indian BTR

I've got a friend who is CrAzY.
He rides a Death Trap
KTM 65cc Water Cooled 6 speed 2 stroke
He say's he's had it up to 70 MPH
Check out his Crappy Wheels, Crappy Brakes, Crappy Forks and Crappy Frame
This is a prototype build.
He is planning on a new frame, wheels and disc brakes.
Bike is fast. Really takes off
