Shocks for 1968 Challenger?

[GrumphFighHunnert]

Hello, again...
Resuming work on my Challenger/BSA project and I am ready to address the suspension.
I have a few questions:
1) What was the stock shock length for the rear?
2)What was the stock shock length for the front leading link?
3) Are the front shocks essentially a standard shock? If not, what am I looking for, specifically?

Thanks-
Johnny

I have a chart of all models. Can you confirm it's an MX4?

Hi Johnny,

Crikey, it's been a long time since you last posted...welcome back!

I scanned and posted three charts that comprehensively detail Greeves original fitment suspension specs on this thread here, in the GRA Members only 'Help & Advice' area of the forum (see Post #6). http://greeves-riders.org.uk/forums/...ear+suspension

Two are original Greeves Factory Information Sheets and the third is a Girling List.

There's loads more valuable info posted in those sections. Being a GRA Member with full access to the forum certainly has it's advantages.....

Hope it helps.

Brian.

It is a 1968 MX4, Brian.

11.9 inch rear, 13.9 inch front for the Bananas do you need the spring poundage etc?

That would be great, Brian.
Thanks much.

OK, the Girling list is as follows:

Front, 13.9 inch total length, unit serial 4928, spring no 9054/90, rate 54 lbs/inch, unloaded length 9.4 inches.

Rear, 11.9 total, serial 2015, spring 9054/58, rate 90 lbs/in, length 8.0 inches.

Those are the standard unit figures. If you fall outside the "normal" weight bracket for riders, you may need a different spring, but your supplier will advise.
