What's stock about pro-stock motorcycle dragsters?

[mikejmd]

I was watching ESPN Sunday night and saw several drag bike races.
I was curious, what about them is "stock" to do a 1/4 mile in
under 7 seconds. How much horsepower do they make, and what equipment is necessary to accelerate so quickly?

COLOR! Black/Grey is what does it. That must be what you saw!

+1 Remind me at the bash that I owe you a beer for that one!

I think the name badge is stock. Oh, and the seat belt too.

wheel base? or maybe frame i'm kind of wondering this myself...

it's mainly about being "all motor" no forced or chemical induction in this class.

Does that mean they aren't turbocharged?

Yup!

 

[Mr Brown]

It like prostock cars. The bodies resemble factory units, but that's about it.

 

[Mr Brown]

They make around 400 horses. Chassis setup is the key to the low e.t. Big motors provide the mph. 160 (2600 cc) inch displacement on the twins, 101(1655cc) on the fours.

It helps when you can run a non-production Vtwin engine because your manufacturer sponsors the class and you get special treatment.

Are you saying that Suzuki is not permitted to run special production engines?

Suzuki teams are VERY limited to what they can do,and use their own factory engines,parts,etc.The Harleys & Buells can do about anything they want.They use engines made by Porche.So don't think for one minute that you are actually seeing a Hardley Abelson beating a Zuke when they win.It's a joke,the only thing Harley on those bikes are the name labels.

Suzis are just this year being allowed to run 4 valve heads. The class is biased toward twins cuz the NHRA wants more sponsor bucks. Suzi doesn't make 2 valve GS motors anymore, so to answer your question, no they don't.
