I have attached a pic to do with the weighing of the bikes at Pembrey
I haven' included specific weights as the owners of the bikes might not want to share this info, but I have listed them in order of weight for each class and included the Front Rear weight Bias.
The amount of fuel in the tank at the time of the weigh in is probably only known to the owner/rider/mechanic and may have some bearing on the results.

mine is right in the middle of the list, more than happy with that considering it's got the std tank and airbox and all.

maybe Roxy brimmed it with fuel
What was the diff between the heaviest and the lightest?
1l of fuel is 1kg

mine was half way down the list, it's not far off, but it isn't that special, I've got a pair of stainless exhaust, std down pipes std air box full fairing, std tank small 3.2ah battery I have chopped a bit off the frame but very small gain to be made there i chucked about 1kg of wiring loom i have a decoded ecu so i only have a rev counter..... I could probably save another couple of kg if I was really worried but I suspect the best weight saving would be the 16st fat bloke on the seat...

in all honesty i doubt theirs that much difference in them,, someones got to be at the bottom of the list, it doesn't mean its 220kg!
Kev, whats the % of difference between the lightest and the heaviest?

I remember a few years ago we had a weigh in and someones class b bike weighed more than Sam Wests Monster road bike,, :)
The fuel can make a big difference. Think they are around 16 litres? Could easily be 14 kg inference between a brimmed tank and one with the bare minimum in.

IIRC it was a Class B Monster then running #34, it has also ran #6, #7 and now #999. I will see if I can find the old figures, doesn't help when your Laptops been replaced a couple of times since then

I think mine is round the 170 kgs. Quite a lot to loose - 916 tanks dont fit the SS? :devil:

mines about 10kg lighter, i haven't got any special bits, in contrast my monster from last year was 168kg and I'd done loads to that, 916 tank it had a 2 into 1 titanium exhaust no air box no filters I'd cut off or chucked away every bit I didn't need. too much really coz bits kept breaking

I would agree with you Simon, but Mike Tesseyman says he's fitted one to his and Alan Ball was going to be fitting one to his. But I haven't seen any photos yet
Simon your bike is a bit lighter than you mention and Scott yours is a bit heavier than you mention
Mine for the record came in at 162kg

I think mine weighed in at over 172 at the last weigh in but I was trying harder to manage the fuel at pembrey. What was my total weight at pembrey Kev?

166.3 Kg
So there were 7 lighter Class B bikes and 8 Lighter Class A bikes
So you did a better job of managing the fuel

How come there wasn't a 2litre left in the tank check too?
Why not post all the weight results, nobody has anything to hide.
.......................................or do they?????? :eek:

Nothing to hide as all are legal
Several years ago when bikes were weighed at a race meeting at Donington, Chaz asked for the weight of his bike not be disclosed. As it was legal then there was no need to disclose to everybody what the bike actually weighed, same goes for the BHP readings.
If the Chief Tech (aka Bernie) thinks anyone is outside the rules he will not only discuss it with the RC but also the Clerk of the course in case an amendment to the results is required.
as for checking that there are two litres of fuel left in the tank, that would take quite some time to do the whole of the grid.
So that leaves two options, either pick some bikes at random or parc ferme the bikes and see if a rider wants to lodge a protest in the given time frame.
The two litre rule is an ACU rule that is written in to the DD regs so that entrants are aware of it.
As you really don't want to fall foul of it as the penalty from the ACU is quite harsh with a 6 month minimum suspension of your race licence during the race season from March - October
Just check your ACU handbook, to me its a poorly written rule as the way it is written seems to equate using illegal fuel with finishing with 1.95 litres of legal fuel. where one could be blatant cheating and the other a miscalculation.
