Two questions:

1. Does anyone know if the header clamps from Speedmoto (in picture) will fit a CB450? Speedmoto says they're for a 350 or 250 twin, with 62 MM centers.

2. If not, does anyone know of another source for aluminum (or other non-rusting) clamps for a 450?

Excellent. My bike sat out in the rain for several days at a rally last week, and the stock clamps got a nasty load of surface rust. Made the bike look shabby. I've cleaned them up with a Dremel & wire brush, but I don't want to have to deal with that again.

For what it's worth, a crude measurement of the clamps on my 450 indicate the mounting centers are about 71 mm apart, so the Speedmoto version for 350's would not fit.

Yeah, I suspected the studs would be wider, bigger exhaust port. I found a seller on eBay with metric studs before - I need to look him up again to get some shorter ones than stock for these from DCC

Just cut yours down. Put a die over them first, cut to length, dress / round off the end, and unscrew the die, to clean up the threads. You can also use VHT hi-temp clear on your old clamps.

For starters, I've removed the clamps, cleaned up the rust with various wire brushes, and put two coats of VHT satin clear on them. I'll give that approach a try for a while, and if it still doesn't keep the rust away, I'll go for the DCC aluminum jobs. The bike normally lives in the garage when I'm not riding it, and I don't ever ride in the rain if I have a choice. Last week was a fluke because I was at a bike rally and we had bad luck with lots of rain.
