Torsion bars and P1 gp.....

1936 Views 19 Replies 9 Participants Last post by  FR
From the USCRA website as to the CB450:

"CB/CL/CR 450 (torsion bar valve spring type head)"

I would interpret that as meaning exacly what it says, 'torsion bar... type head' ....TYPE HEAD. It does'nt say restricted to using the original torsion set-up.

Anyone have any further info or comments?

Rosko,
Dude, I've been trying to find out if there's a measurable wear limit for the torsion bars, no luck so far. I've only heard back from KA Performance, who doesn't build stuff for the 450, only the 350 and 750. He turned me on to the WorldCycle dude, who used to race the 450 back in the day, but doesn't want anything to do with 'em now. (But he's cool anyway, 'cause he builds the coolest CB750s)
E-mailed the Henning/Harsh contact last week, haven't heard back...
From the research I've done so far, the swap of the torsion bars (flipping them from A to B) is not a reliable exercise, it's been done, but I guess not recommended for road racing. Don't know about the cost of the conversion to coil springs, I think I may have seen something at Megacycle's site. I'm not gonna bother, 'cause I'm not expecting miracles out of this thing anyway. Diminishing returns and all...
By the way, thanks for the offer on the CL wheel. Mine did show up, and it's in decent shape, so I'm good to go.
