Weighed my 07 track bike tonight

Used digital crane scales borrowed from a similarly-inclined mate, the sort of thing you see at a fish market. Tank had probably 2-300 ml in it, all other fluids topped up. Sidestand was mounted on the bike for manhandling round the garage, but I forgot to sit the side covers on it. Took a vid of it on my phone, but 93 Mb is too big to post. After adjusting for the sidestand and side covers, it comes in 153.75 kg (about 339 pounds). I was hoped it would be around 150, and no more than 152, so I'm a bit disappointed - must try harder !

Cheers,
Brian


Do not walk behind me, for I may not be leading.
Do not walk in front of me, for I may not follow.
Do not walk alongside me, for the path may be narrow.
Just piss off and leave me alone.

^^^^ I trust you are kidding us, good sir? At 153kg you are more than 10kg below minimum weight for WSBK. Astonishing. Well done.^^^^

Interestingly, it says something about race bikes (particularly in MotoGP, an alleged prototype class) being far too heavy.

Regardless of all that- very well done!

Thanks mate, I've spent a fortune to date, and with about $10k more it'll have gone about as far as I can make it go in weight terms. Around 38kg removed to date, I believe there's scope to take that number over 50kg, but not sure I'm going to go that far.

Cheers,
Brian

Hi Brian,

I am a bit confused. Is your bike a ZX-10R gen4? If so, as I presume, the standard weight is, I believe, 198kg.

Surely, if you are at 153 ish, you have removed 43kg not 38. Is it my and/or your poor maths or am I missing something?

No, it's a Gen 2. Published weights seem to be generally understated; as an example, my old ZXR750 (ZX7 in the US) was quoted as 205 kg dry, but actually turned out to be 225.

Based on what I weighed tonight, and on the amount I've painstakingly measure as taking off the bike, originally it would have been 191.7kg half-dry (that's all fluids except fuel).

There's a few pics of various components under my gallery postings, will post up a couple of up-to-date pics tomorrow, but unless you look closely, it's nothing obviously special. That'll change when my ex-BSB frame and swingarm arrive from England, but right now it looks like any other trackbike (albeit with Ohlins, BST, Akrapovic, etc).

I took a vid of the weigh-in on my phone, but at 93 Mb íts too big to post - not sure how I'd get it hosted.


Cheers,
Brian

The best way to post a bigger video is to post to you tube or vimeo and then post the link here, I think.

The weight limits have steadily increased in GP's to try to slow the bikes down. They would likely be 75 to 100 pounds less if the rules allowed. I remember when some of 500's weighed just over 260.

^^^^ although 2 strokes will always be significantly lighter than 4 strokes by design.
