Fastest Doodlebug!

[isaiah3g]

On my way to work thinking about minibikes (it's all I think about!) wondering who has the fastest db?

I have a db30 old style that does between 50-55.

I'd like to see what everyone else is running.

Isiah, check out the Michigan Mini Bikes on Facebook.
Those guys are building some baaaaaddddd bikes up there in the frozen tundra.

 

[isaiah3g]

Just waiting on a confirmation!

I have one that was running in the mid 60s @ 10.8 seconds in the 1/8 last year

 

[isaiah3g]

That's cool vwfan. I've never been time trapped but have made several passes down a drag strip.
It was an old school flag drop race at atomic blast. Its a rat rod event

my buddys that came to Alabama with me are the fastest ! Fastest to crash that is !

Those alcohol fire breathing ones? Too fast for me, ever.
