did we ever come to a conclusion about the alloy swingarm for the pre'78 RM125's

[GMC]

On another note I see the rise of after market replica swing arms, I suggest that if you have one you have a period photo or period catalogue showing its availability, only with this proof will it be acceptable.

211

Could you clarify that abit more please.There are alot of reproduction parts being produced thesedays not only swingarms but frames , pipes ,rear shocks etc.by Novation ,GMC,Vintage Iron,ProFormRacing,DG,Circle F,YSS,Techno Flex, etc.

Pipes & shocks don't come into it as they don’t have to be replica’s to be within the rules.

And please, whinging that some other part is allowable doesn’t mean your part should be.

Doc seems to have put forward some good evidence for the RM swingarm that I think should make it allowable (but I’m not a scrutineer)

If you want to build something outside the norm then put some decent evidence together like this, not hearsay from some mate’s uncles cousin

[motomaniac]

Yes I agree with DOC's point of view also but what I qouted(from 211 kaw) goes beyond and has  much more wide ranging implications than just the RM alloy arm issue.

I haven't read that rule about the pipes and shocks Geoff but for sure I agree that you can't spout off about something that you heard or saw without evidence .
Myself I don't run Fat Bars , my suspension is period restored but my swingarm is reproduction.
Just wundering

This is starting to border on ridiculous fella's, Mainline, do YOU think that that RM125 Fox replica is pre 78 legal?, that bike has more suspension travel than most EVO bikes!!! and as for the swingarm, well I'm pretty shaw that it never existed back in the day?. Why is it that some people want to change the rules?, we have a set of rules already. Doc, if you want to build a bike that you know doesn't fit the rules for the class YOU want to ride it in, why not ride it in EVO, whats the big deal? If you just want to build a TRICK bike that you've always wanted go for it but why stir it up when you know you can ring Dave Tanner and find out the DO'S and the DONT'S? The big question is " are you going to bring it down and ride it"....... probably not, so why stir it up? 

jeez, calm down. I wouldn't have a freakin clue whether it was legal. I just remember seeing the pic on a while back and then when this thread came up it reminded me of it. It's a nice looking bike, that's why I asked the question. You could give me an actual works bike to ride and I'd still finish last, so the reason I asked was purely out of interest. Not because I want to cheat.

The rest of the pics of "my" bike are here. http://www.vintagefactory.com/1977_motox_fox_suzuki_rm125.htm

lighten up everyone for gods sake.

18.3.0.4   Exhaust may be modified but must generally follow original lines.

Can’t actually see one for shocks but their isn’t any thing to say shocks must be original either.
Just
18.5.0.8 a & e which states that travel should be within 7/4 limits. (this is one of those rules that needs to be moved from the general section to the pre 75 section)

18.5.0.1 Replica frames are acceptable provided they follow original lines etc. etc.



18.7.3 Table of acceptable components pre 65
Handlebars – all including alloy

I believe this rule was made to alloy pre 65 the convenience of using any bar & not be restricted to only using steel bars.
This was an early rule that didn’t foresee fat bars & the rule didn’t move with the times.
I don’t really care about the use of fat bars other than they just don’t look right.

I see a lot of guys bang on about adjustable shocks but from 5 feet they just look like shocks to me.

Why is it that some people want to change the rules?,

because the rules blatantly suck, discriminate, are a limitation to the sport and because we can .

What would you change if it was upto you?

Pre'78 would mean pre'78. The 77 VB Monty  and the 77 Husky should run in pre 78. The designated year rule that affects the Bully as mentioned by Firko should be changed or interpreted differently. Hows that for starters? .

[holeshot buddy]

gee i like your bike mainline

i have a thor  alloy swingarm on my rm370
with non floating brakes
works good looks good and staying there

[Davey Crocket]

Took you 12 hours to come up with that, your mind must have been working overtime . If you read the rule book it explains why, I think? Help me somebody here.

Geoff

18.3.0.4 basically then anything goes execpt change an up pipe to a down pipe or visa versa.
18.5.0.8 Agreed.
18.5.0.1 So doe sthat mean a replica of a period aftermarket that was a modification from standard specs is allowed?

Fat bars and the adjustable shocks argument only really  came up after the pre 78 protests at the nats.
I agree they don't look right and if they are of no advantage why go to the trouble of fitting them?
Anyway I think that they are covered along with the shocks in several clauses in the Evo AND PRE 85 sections. I wouldn't care that much either except for the hypocracy that DOC also pointed out.
Rubber mounted handlebars and welded on brake tabs look the same from 5 feet (showing you age .we went metric in 73) away also.

cheers

Hows that? For me personally that would be a change that I totally agree with .

Yes, it's generally accepted so long as you can prove that what you have is what was available.
Some common parts aren't questioned, well, because they are common, but oddities will need some documentation.
My CZ frames are replica's of USA aftermarket frames & they are accepted worlwide.
Same goes for the HL's

We may have gone metric Brent but I still have 2 feet

Davey, go polish your stands

You'll be right Brent, it's only ever a problem if you win

25 years next feb ya know!!!

Hey thats right. 25 years & I still haven't scanned all my slides

[motomaniac]

This is getting like the sidecars , the ones from that period want it they it was and the newbis want it the way they  want it to be . Perhaps Cyber VMX is the new class 

Im not a newby , I set my bike up as close as possible to the one I had 30 years ago.I did that for nostalgic reasons and also because I knew it worked good.
I suppose the point is that I didnt specifically build it for a one of event. I have 2 good years of racing on it so far so perhaps I shouldn't be worried about an extra 9 laps at a Nat event.

Yes and that's the hard part about it --you or most vmxer's didn't  build a bike for a one off event--the eligibility has to be pickup up at club level ,On any Sunday.  Preserving an era.
