If a YZ 465 H 1981 model was fitted with a seat and tank off a `82 model ( which has linkage suspension ) still be eligible for EVO class or would it become a Pre `85
-
still evo
-
How come
-
Thanks for the manual E
-
How come
Because Evo is a technology class, not an age class.
You could fit the seat and tank of an 09 YZ450F, and it would still meet the criteria.

Here is an example that will cause some controversy. It is an '82 YZ490J, that has the original linkage & swingarm replaced by an '81 YZ465 swingarm ( which fits straight in & attaches to the '82 shock ) . The UK guys look to have a few of these running in their twinshock class , which is equivalent to our Evo class . I actually don't have a problem with it , as I couldn't see it being any better than an '81 Maico 490 which is generally regarded as the best bike in the class ( except by a few misguided individuals ;D ). It would make a use for a bike that is not a very competitive pre'85 class bike & I might even build one up myself , to sell locally & get another bum on a seat ( as we need more evo class numbers in my area ). I know this bike would cause howls of protest if it ever showed up at a title meeting though .

Here's another one with a custom aluminium tank .

Might be a good way to get the rules sorted out properly, though?
-
I'm not sure about the big bore ,but the IT250J is EVO legal as it is Monoshock what was the bigbore ??? . These might be just modified IT's .
-
IT465J looks just like an IT250J with a fatter pipe.
The possible drama with the converted linkage-rear bike is that the 490 motor didn't come in an originally Evo class bike. The reality is that it meets the criteria, so it is legal, but some people don't see it that way.

The reality is that it meets the criteria, so it is legal, but some people don't see it that way.
The 2009 Manual of Motorcycle Sport (MoMS) says what the criteria is.
It says:
17.7.12 Evolution Class - Eligibility
...
18.7.12.2 Modifications converting later equipment to comply will not be allowed
So it is not legal.
-
you EVO guys are the future VMXer's as the pre 75 move on in years.....
so get it right and make the pre 75 movement proud of you. 8)

"18.7.12.2 Modifications converting later equipment to comply will not be allowed"
So it is not legal.
Easy to side step. Call it a 2009 model Teddles490 on your entry form and you're home and hosed.

i spent quite a lot of time reading this today
http://ozvmx.com/community/index.php?topic=3802.0
the more i got into it the more i think the 78-85 era rules/classes needs to be somehow cleared up/changed

I am a scrutineer and I would not pass it.
18.7.12.1 Bikes will be OEM
Yamaha is the Original Equipment Manufacturer, not Nathan or Teddles.
Yamaha manufactured all of the Major Components of the bike in 1981.
Now back to the original question.
Evo is not a Period. That is why you can enter a bike in both Pre 1985 and Evo at a Championship meeting.
The Period of the 1981 bike and the 1982 seat and tank are Pre 1985 and so they conform to rule;
18.7.12.3 All components will be of the period the machine was manufactured
Therefore it is ok to use them.
-

No it wouldn't.
-
SRUITINAZI!!!! ;D ;D ;D
-
If the bike is entered as a Teddles490, you have to accept it - and any arguments about how "it is just a bastardised 82 YZ490" won't hold water, as many manufacturers use parts from other manufacturers...
Similarly, the word "later" is totally meaningless when there's no age limit on the class.
With "major components" left undefined, the seat and tank swap is merely in bad taste, not unacceptable.
Yes, I am playing the loop-hole game, but the point is that the loop-holes are there.
-
If the bike is entered as a Teddles490, you have to accept it ...
No I don't. If there is any dispute:
12.2.1.4 The onus of proving that a competitor, and the competitor's machine and clothing, are eligible to compete, is on the person seeking to prove it.
So he would have to prove that it is a Teddles. What documentation do you think he could find to prove that?

Tank and seat are not major components. But the Evo rule doesn't say major components it just says components.
Yes, I am playing the loop-hole game, but the point is that the loop-holes are there.
And there is also precedence.
As well as rule:
12.1.0.3 Everything that is not authorised and prescribed in this chapter, or in the discipline specific chapters, is strictly prohibited.
But the main thing is the intent of the rules.
Philosophy of GCR'S
The General Competition Rules
The philosophy and structure of the General Competition Rules
No set of Rules can anticipate every issue which may
arise in the conduct of a sport, especially one with as wide
a variety of disciplines and competing interests as exist in
motorcycling. The philosophy of these Rules is that good
sense, cooperation and a fair and reasonable interpretation
of reasonable Rules should be more important than "Rule
Book Racing".
In Rule Book Racing, if a situation arises, the answer is
to be found by looking up the book, not by the exercise of
independent judgement. If there's no answer in the book,
a new rule has to be devised to "plug the hole". Rule Book
Racing assumes that Controlling Bodies have little or no
interest in working effectively with competitors, with each
other, or with Promoters to benefit the sport and those
who participate in it. It also assumes that officials have
no common sense or understanding of the sport. None of
these ideas is true or fair.
These rules confer on the Controlling Bodies and their
representatives and officials discretion in the application
and interpretation of the Rules. It is intended that discretion
will be exercised, as stated in the very first rule in this book
to ensure that competition is safe, free and fair.

1.2 PURPOSE OF RULES
1.2.0.1 The purpose of these Rules is to regulate
and control motorcycle competition.
a) The Rules are to be interpreted with
the intent that competition will be
safe, free and fair and conducted
applying the principles of natural
justice.

If you build the bike, you can build the documentation.
You're still assuming that you're looking for a historical precedent and/or proof that something was built before a certain date.
Tank and seat are not major components. But the Evo rule doesn't say major components it just says components.
Fair call - I was wrong. I am also wrong to have modern rims, grips, tyres and handlebars on my Evo bikes...
:o

Now that's really interesting. Why hasn't it been quoted ad nauseum in previous rule book threads?!
It is no excuse for having crappy, poorly defined rules, though.
I have zero interest in pushing any of the points that I've made - and my own sense of right and wrong would mean that I never will.
But the namby-pamby stuff about "safe, free and fair and conducted applying the principles of natural justice" is just inviting someone to play games, while leaving those of us who try to build our bikes right open to being jumped on by an over-zealous scrutineer or steward.
-
It is better for us all if we do not promote "Rule Book Racing" or breaking the rules.
History shows that if MA think that eligibility is getting out of control then they will act on it.
MA thought that Unlimited Period 5 Historic Road Racing was getting out of control and cracked down a few years ago.
The next year the grids were way down and many left the sport.
But it was a good thing in the long term because it reduced the cost of the class and these days look how many turn up at the Island Classic and Barry Sheene.
The option that they have to sort out Evo would be to implement Historic Log Books.
Then we would all have to apply to MA to be allowed to race our bikes.
They could use it to enforce their idea of OEM if they wanted to.
Wouldn't that be sad if you had paid $2000 for a set of trick forks and then had to fit the original Yamaha ones!
-
I've said before log books would be a good thing and reduce eligabilty dramas very quickly.
-
Nathan may or may not be right about loop holes being their but how about it if all the wood ducks whom look to exploit the loop holes (if any) for there own advantage go away and annoy another sport.
It's not a hard game, we can make it easy or hard for the volunteers that do there best to control/administer this great sport.
