Motorcycle Front Forks

[Tswami]

I'm going to be running a 750 2 stroke in a drag frame with a solid swingarm (no rear suspension) and I'm looking for something to run up front. Are there any special considerations when trying to decide? Do I need a large diameter fork or will smaller work fine braced? After I decide how should I set up the stiffness on them? I'm familiar with setting them up for proper street riding but do I need them more rigid?

I plan on running at Loring and at Bonnevile so I'm sure the asphalt is completely different from the salt so suggestions for both are appreciated.

I run a CBR1000 rigid with a stock front end with stock springs no problems so far!

Maybe a picture of the bike would help a bit.

She's a long way from done but you can at least get an idea.

Drag frame - rigid rear, Buell S1W front forks. Laydown bikes are not uncomfortable on the salt flats.  On the paved courses like Ohio and Loring it bounces you around a bit but no enough to cause concern.  I would use a good set of inverted forks from a crotch rocket (Suzuki, Kawasaki, Honda). They are  plentiful and cheap enough online.

Doesn't look to be a H2?

Thanks 55, I know its not about the looks but I was hoping to use a spoked front as well. Not a big deal, I'll do whatever gets me down the track. The steering stem has to be tiny, but I think I'll have something machined to put what I need up there.

Ransom, it is in fact an H2 motor. Thats a street H2 project behind it too. There won't be much else H2 stuff on it except the rear hub.

Because you don't need front brakes, except at over 175mph at Loring, you will have a lot less load on the front suspension.  I ran 33mm CB360 forks and rigid rear on my BSA B50 with 2" ground clearance and no problems at 119mph.  I don't think you need to go overboard, but then, they didn't call those things "widow makers" for nothing!
