2010 VMX Tri Series

[JohnnyO]

Evo open had qualifying races.

[BAHNZY]

How many classes you can run in a single day is a simple mathematics. The current proposal for a class structure is;
Evo 125, 250 and Open
Pre '85 125, 250 and Open
Pre '90 125, 250 and Open
Under 45
Over 45
Clubman
Intermediate
Expert

Assuming that;
There are 14 classes
A race is 3 laps (although I am guessing that the Pre90 guys will want 4)
The lap time is 2 minutes on average.
There is 3 races’ per class.

14 classes x 3 races = 42 individual races
42 races x 6 minutes per race = 252 minutes (4.2 hrs)
As long as there are no hiccups during the course of the day, my experience with this would tell me that I would need about 6.5/7 hours to run the day out. If the track is set up in such a way that the next race can start whilst the other is still running then you have a better chance to stick to the time. As much as it pains me, we are in a sport where it not a matter of if a rider gets hurt, but when, an accident can stop the program for more then 30 minutes and generally you cant recover that time.

As most tracks now have curfew where a bike can’t start till 9:00/9:30 am on a Sunday (local council dependent) then you are looking at a 4.00 pm finish.
If the lap time is less then you are better off by about an hour, so perhaps a 3.00 pm finish and none of this factors in a lunch break.  Either way a single days racing wont support much more than 45 3x3 races.

So if you add Pre75 classes then you would have to run it over 2 days or drop classes from the original schedule.

Note:
Pre78 has been mentioned but not included in the above.
There is no provision for qualifying races

What about the 100cc dunger class? At last, a perfect place for them!

[Rossvickicampbell]

actually Bahnsy thats a good point and one bought up previously as to why the Nats were over 3 days and 3 lap races - couple that with really requiring different tracks and to include pre 75 just aint going to work.

I am just going back to my box now

Without much/any fuss or bother, Heaven 'always' manages two rounds of:

1. Ladies/Pre-70.
2. Classic 125.
3. Pre-75 250.
4. Pre-75 Open.
5. Pre-78 250.
6. Pre-78 Open.
7. Post-Classic 125.
8. Evo 250.
9. Evo Open.
10. Pre-85 250.
11. Pre-85 Open.
12. Pre-85 only.
13. Four stroke.
14, 15, 16, 17. At least four junior races wedged in the middle.

The juniors get two laps, seniors on older bikes get three laps, the newer bikes get four.

So, two rounds of seventeen races = 34 races. With a (rough) average of three laps per race = 102 laps worth of racing.

The proposed Tri-Series format has three rounds of fourteen races = 42 races. If each race is three laps, then you've got 126 laps of racing.
If the format was tweaked to make it two rounds of four laps, then you'd have 112 laps of racing to get through. I also suspect that this would be faster as you spend less time waiting for the track to be cleared before starting the next race.

(NB: "Laps of racing" is the total number of laps that need to be completed in every race. It has nothing to do with the number of laps any punter would do, unless you entered [and finished] every single race on the day.)

If the whole idea is as poorly supported as some suggest it will be, then I'm sure there will be no drama with combining at least some of the races.

Can anybody tell me what Pre 85 only is? (I'm guessing it's the politically correct "no twin-shocks here thank you very much" class)

Why only 2 rounds of racing? If i was driving 1000k's to race i'd want to do at least 3 rounds, especially if i was travelling with a mate and we only took 1 bike each.
I like the program Bahnsy has listed, less classes(assuming that they combine some of the smaller classes), more rounds and hopefully 4 or 5 lap moto's.
Are the Clubman, Intermediate and Expert classes for modern bikes?

[Nathan S]

Ross, This is the simple version:
At Heaven events, the older big bore bikes all get to 'ride up' an era - meaning that everyone gets two rides per bike. The club rules say that you can enter a bike a maximum of two classes.
Obviously the Pre-85 Open guys don't have that option, so the pre-85 only class was created to give them a second class to ride. Other capacity pre-85 bikes also get to ride in this class, so its not just a re-run of the pre-85 open races.
Yes it means that the older bikes are excluded, but they all get a second ride anyhow.

JohnnyO, yeah, that's entirely fair enough too. I was just floating ideas and trying to keep some perspective on the "can we fit all of the races into one day?" part of the discussion.
If there are modern races as part of the programme, then presumably you could enter your old bike in that class too, which would give everyone anotheer ride.

[All Things 414]

How do you define 'older' though?

[JohnnyO]

How do you define 'older' though?

Not 'newer'

[BAHNZY]

This is a little of the original thread but still addresses the point re Pre85 / Evolution.
Under the current GCR's the Evolution class is a all but a waste of time where there is no riding up a class rule in place within the GCR's. If you were smart (under the current GCR's) you'd build a good solid Evolution bike and run it in the Pre85 class as well.

[All Things 414]

Montesa and Maico already have.....

[JohnnyO]

Bahnsy if a round was run in Vic would the support classes alongside Evo, Pre 85 and Pre 90 be modern bike classes or more vintage. What works best down there?

[BAHNZY]

Johhny O,
It would depend on what you are trying to achieve.
If it is about making a few $ for the host club then you have to run it alongside moderns. At an event like that you would attract a full field of moderns from within the hosting club and the MV District that the club belongs to. That brings in good money. However the down side is if you have a Pre90 or Pre85 specific bike (where you cant run in EVO) you'd be a little pissed off that you travelled a thousand or more km's to race at a VMX tr-series event and got only 3 races when there is a modern grid getting 4 x 4 laps of racing. If it was me i'd be asking why the modern class isn't dropped and and extra round (or lap per race) is added for the Pre85 and Pre90 classes.

For what its worth, don't even entertain a Junior class (either modern or VMX) it's just to much hard work. In the end it's all about making the thing break even and putting a few $ into the hosting clubs coffers.

[JohnnyO]

I was just wondering whether you would need the moderns as support to make up the numbers. I would rather see it be an all vintage meeting if possible with the main Tri Series classes being Pre 90, Pre 85 and Evo.
