Just looking through the printout that I was given at SVA and it tells me the axle weights with and without driver but I know that they drop it slightly when it goes onto the rollers/scales. What would be the rough weight do we think? Do I just add the axles and minus my weight, is it as simple as that?
Axle 1 no driver:178
Axle 2 no driver:220
Axle 1 with driver:198
Axle 2 with driver:270
I weigh around 68.25 Kg. (Solid muscle )

There's always some debate on the addition of axle weights to get the toal weight (it's not as simple as just adding them up)

In practice the best bet is to find your local public weighbridge and get it weighed. My local one was at an aggregate depot and accurate to the kilo and cost about £6 IIRC. My Pnto'd Indy weighed in at 598kg with a tank of fuel (not including me though).

Weights you quote don't look at all out of place for the BEC.... however. if you've got to be accurate then adding up the axles (or even corners) is fraught with weight transfer, angles of rake, torsional components and the like.
Do yourself a favour, buy a set of cheap bathroom scales. One each corner will do (if lardy scales) or two each corner with a bridge across each. You can then use the scales for corner weighting when you make mods/circuit use, etc. Mine are non-lardy ASDA jobs, bought a few years ago, have done a lot of use since!

Lets just say Chris, including driver, yours is defiantly lighter than mine

Come on and get yours done Gav.
The weight doesn't need to be bob on I was just after a rough idea. I have an ADA corner weight thing that you put inside the wheel arch but I keep forgetting to get a new gauge for it and when the DVLA sort themselves then I can get it to somewhere level. Garage is too tight and drive's on a slope with a steep camber on the street.

Well once its registered you will have to bring it round mine and do it on my nice flat drive

Its taken 2 - 2.5 weeks just to speak to the man who knows what he's talking about. He was given my number 3 times and it failed to materialise in full all 3 times and no one would tell me his phone number, like its some kind of top secret. I've got it now though Oh and be prepared to haul yours back to Chadderton. Apparently he's the only one capable of reading chassis numbers in Manchester properly and he won't let you drive there and he will only do them on a Tuesday! Bloody joke, anyway I digress.

the westy megabusa weighs in at 495kg plus driver n fuel if thats a nearby help

Ah yes that helps Sam. I thought it was massively overweight otherwise. Ta.

Sorry, yep, I understand now. You're just interested in a ballpark of what a BEC should weigh. I can tell you definitely that:

Westfield MegaBusa (Hayabusa, dry sump, reverse box, factory spec everything, some minimal interior, wet, on the road) - 492Kg

Westfield MegaBlade (above car with a Fireblade 893) - 462Kg

Westfield MegaThump (above car with a TL1000R) - 471Kg

Westfield Mega (above car with a GSXR750) still road legal, but losing a lot of junk - 432Kg

Above car, less reverse box and props, electric substitute, all junk removed, one seat, but still road legal - 407Kg
