Swinging Arm Rules

[mrequipe]

What are the rules on swinging arm for post classic ? Can they be single sided ?

[ACER]

As far as i know the swinging arms can be double or single sided. Cheers !!!!

Thanks for showing interest,
The pre-injection class rules are very simple, 3 wheels and carburettors, any engine any chassis.
Please contact me if you require any more information.

But the question did not relate to the new anything goes class, it was post-classic specific, from a man who knows a bit about sidecars

I would take into consideration where your customer intends to race the new bike,the European races still have a Post Classic class that runs to proper rules,unlike us.
When I went to Gedinne in 2012,Gordon Jones went with his 350 outfit.He was excluded from the results,and made to start from the back of the grid,because he was honest about the age of his bike(1992 I think)but the rules were pre 81,I think.
Can not be sure but definently worth checking before building the bike.Hope this helps.

That's partly true Tony - excluded from results would be more accurate...so...(BTW - think it was 2013 you did Gedinne)

You are right - the Belgians seem to want some more interesting racing - and do specify age / year limits -for all the classic / post classic sidecar classes - although I don't think it's written down - the year of the chassis is generally - I think - accepted that 30 / 40 / 50 year old frames are past their best - so - as we all know - there are lots of very new chassis out there - BUT - I think the idea is that they are of a design / construction that would have been built in the relevant period - so safe old bikes...

The 1982 cut off for Post Classic in Belgium would certainly allow the use of any TZ up to "G" - the last of that model (I know they did a few "H" models- which were effectively the same) - same with your TZ - and in fact - your bike with original chassis is probably closer than most to original.

The confusion / exclusion came about (It was applied to Paul Owen as well) when one of the younger competitors saw a 350 2 stroke - and complained about it - he'd never seen a proper TZ and thought it was a YPVS (he wasn't even born when the YPVS was current) - which - being introduced after 1982 - would have been ineligible - we informed the organisers - and the exclusion was lifted.

As for single sided swingarm - I believe there were plenty built before 1982 - and have a few pictures if you want to see them...

As a footnote - anyone entering the Belgian races should check the regs - they are easy enough to translate enough to understand the meaning - and it's easy enough to find out when your particular type of engine was first produced - something like an FJ1100 Yam for instance was first produced in 1984 - so would be not eligible - other stuff like "no floating discs" etc etc...

If you turn up - they are unlikely to stop you riding (I'm told) - but they may exclude you from the results..
Also - make sure you have a back protector in your leathers - they are quite strict on that...
