Back in the day in club racing in the UK when you could find yourself on a grid with 30 or more sidecars on it was just awesome ,, but back in the day they had an open class ,, you run what you brung ,, bring that class out and watch the sidecars grow :D :D :D :D :D :D :D :D

Ditto.....what Steve said.
To accomplish any of this, does a proposal need to be made at the AGM? What's the process?

Rule changes are done outside of the AGM, the procedure is in the Constituion. The AGM was used to allow a one year trial of the GP class. The rules were refined after the trial year and submitted to a vote by ballot. The trial run of modern GP bikes was done at the AGM since all modern classes were cancelled at an earlier AGM by a vote.

Replicas in any class are always problematic since materials, construction techniques and structure design are taken from modern technology. A replica Manx Norton will be much better and faster then an original, likewise a ZX7 frame built using modern techniques and finite element analysis would look the same but be much stiffer and lighter.

Not a fan of the exhibition round, time should be tight for racing. Lunch or end of day are possible times but how much interest is there from racers/owners with special rigs to attend?

If you remove replica machines from the grids there is no future in vintage racing.

There is plenty of latitude within the current build parameters to assemble and race a very competitive machine. Is Ralf's rig still for sale? A great starting point.

I gree with Jim that to remove replica bikes from the grids would be a bad move.
I don't think an extra class for the sidecar grid would hurt it at all.
Add it to the existing race.
We did it with the MGP bikes and they aren't even 'vintage'.
And as we have seen, interest and desire does not indicate actual numbers on the grid.
So what's to lose. 'Replica's' already make up the vast majority of the grid anyway.
Sidecars have a small grid and yet are an extremely popular spectator class. So, why not encourage different machines? Seems we do it in other categories.
Simple enough.

Feel like I'm flogging a dead horse here, so I will leave it be , if someone would like to take this up, I'm with you.
Otherwise....bollocks.

My reference to replicas is a bit misleading. What I meant was a replica of a bike that, although it appeared as a one off or works machine in the period, does not meet our rules for that period. This would not include things like ‘new’ Manx Nortons or G50s as they meet all our rules for period 1, although Dave Roper did say to me that he would not enter the reproduction Manx in the pre-65 class as he felt it does not meet the spirit of this class. Things like replica Drixton or Harris frames also are OK as they fall within the period rules for frame construction and were made in the period.
As for the chairs, even Rudi’s first Cat with tubular frame and leading link forks was fitted with Mini wheels and was incredibly low (the handlebars were 12” from the road!). Sidecar constructors have always been very innovative, from the Owen Greenwood Mini based machine in the mid-60s to the later 3 wheeled racing cars with powered sidecar wheels, hub centre steering and formula car type suspension all around, all running on yard wide ex-F1 slicks. This progress culminated in an abortive move by the FIM in the late 70s to bring these machines back to something resembling the concept of a motorcycle and sidecar. There was widespread complaining from the competitors so the FIM came up with 2 different classes of sidecar for the Grands Prix (B2A & B2B). This was also unpopular and the sidecar class disappeared from international racing not long after.
As for Steve B’s comment about run what yer brung! What are you thinking Steve? :shock: The whole concept of vintage racing is to replicate, as far as possible, racing as it was in each of the periods. By allowing out of period parts or machines it just raises the anti for everyone else. Yes, we all go out there to win but what does it prove if you have later technology parts or machine. Like Steve Hoffarth writes in last month’s IM, vintage racing has many advantages over modern racing, one being that vintage bikes do not become obsolete as they are already obsolete! If unlimited mods are allowed then we just join the treadmill that is modern racing where the bike has to be constantly updated to even stay in the same place. I think that, for all the reasons Steve points out in his column, is why we continue to attract very large entries while modern racing is dying.
My thoughts, anyway.

Thanks for the reply Stan, I mostly agree with all the points you make, but if in the 60's and 70's racers came up with innovative ways to try new things, why are we not encouraging our members to represent these innovations. What P2 class or championship are we replicating right now?

The question I wonder about is, how many others would build sidecars if all period replicas were allowed, are there enough to warrant creating some kind of P2 sidecar GP replica class? Even if scored separately, if you get 4 more rigs out there....

disclaimer: I know nothing about sidecars, I don't intend to build one or submit a rule change, I am just asking questions...

When in doubt, gas it!!!

Just an old guy with a question.

Whatever happened to the Murphy/McCallum P2 rig? Honda CB750 and at WERA it was 1100CC

I should know better than to stick nose in but; having built two replica P2 rigs last winter a BMW and a Yamaha, I built a 10" car wheeled kneeler rig with Disc brakes in 69. We toyed with a V6 Chrysler outboard motor . There were basically no rules in Canada at that point. The P2 rigs in VRRA are essentially state of the art here in about 1970. If some one wants to build a Genuine replica (is that an oxymoron) of a world class special, they can run it currently with SRA in F2 or F1, why do they always want to run in a class that gives them an advantage? How about building a replica of Klaus Enders World Championship rig which sits in Vermont or Chris Vincents TT winning BSA rig both of which still fit VRRA rules. Currently in the British Motorcycle Museum near Birmingham. Paul.

anyone who feels they should be allowed to use later technology to circumvent the rules; larger motor, upside down forks, aircraft construction frames etc. pushing the envelope is normal in state of the art competition, it is IMO destructive when applied to the "vintage concept".

No....the point is ....it is a 1970's genuine attempt at a replica.....just like all the other P2 1970's 'genuine replicas'.
That's the point. How fast it goes is not the issue.
As we all know, it's not necasserily the 'fastest' bike that wins.
We should do everything to encourage new members , new rig ideas, and diversity in the paddock.

I was just pointing out how to get moor sidecars out to play,,, I can not see how making the grids larger could be destructive :shock:

It could be destructive if we implemented changes that prompted
an arms race. Making existing rigs less competitive could cause them
to stay home. Seems pretty straight forward concept to grasp.
I'm all for more rigs. And I'm all for change, but let's be careful
moving forward please.
