Some ideas:
- go through the bike and get rid of parts you don't need.
- Only use steel bolts if its load bearing otherwise use plastic bolts or cable ties.
- Do you need to fit washers? (these obviously spread the load in certain places), or can you just use loctite?
- use cable-ties to secure parts to frame (dump mounting brackets)
- Do you need a battery box?
- Do you need a rear hugger, a chain guard, plastic shields, etc?
- fit a steel tank
- Make sure you've got very light clipon bars
- Only fit a nose and belly fairing, and make those minimal
- don't fit crash bungs, what do you save?
- use really light faring brackets and make them as small as possible
- any bolt threads that go through a nut (and protrude through) are not needed - cut the ends off - loctite.
- dump the airfilter

For the seriously commited (all of us!!)
- get a 2-1 exhaust and get as much Ti in it as you can.
- use a 600SS frame (I didn't), these are the lightest frame eligible in DD.
- use a single disk/caliper
- make sure you just carry enough fuel to get through the race, measure and calibrate (but you do need 2ltrs at the end of the race for ACU rules though).
- get light leathers, helmet (X-lite?) etc...

- you could remove all paint from the wheels and frame too.... more weight to save!!

Finally, before you race, cut your nails, pluck your eyebrows, take a dump, blow your nose and have a w**k,

Enjoy.

You missed "GO ON A DIET", I'm still trying but love my food.

As for the removal of paint from the fram, does sliding it along the track and into a gravel trap do a good job or would taking it to a proper sand blasting place be better

Every little helps!!! - but I missed a few tricks with not stripping the frame and wheels of paint though and many other ideas - I feel a book coming on!! If only I'd had another year!!

You get it to 150kg for Class B and we'll have to find you some lead, about 4kg worth.

My bike weighed 173kg but by laps 9 and 10 of the second race it felt alot more.
I already have an alloy arm to fit and will be looking at fitting some lighter silencers, would much prefer a good 2 into 1 but they cost.

A lot of weight can be removed without going mad on Titnium, etc.
Dallas's bike has a standard Steel SS swingarm and a standard tank,
I know I could shave a bit more weight off it without going for n Alloy arm, alloy tank or later typrrear wheel, but that would put it close to the 154kg limit at the end of a race with just 2 ltrs of fuel in it


Tomorrow I'm back at work and the spread sheet is on my office PC so I'll enter the details of those that have given the OK to do so and put it up.

Here's some food for thought

M620/M600(1999 -2001) forks and SS top yoke = 8.7kg
Ti race can = 1.5kg
early SS frame (standard) = 10.4kg
Alloy arm = 4.1kg (I think hat included the rear spindle)
Carbon Cans = 1.7kg ea
Link pipe for above 0.6kg
WP Emulsion shock = 2.6kg
later type rear wheel, disc & Diablo = 13.2kg

I'll way some other bits when I have some spare time
like standard SS bars, alloy clip-ons, fairng brackets etc

would have been interesting to have anothwer column, with the riders weight also

[rossco572]

No thank you!! and i'm sure that the ladies amonst us would also like that kept a closely guarded secret!! To be divulged to only my doctor or undertaker whichever i meet first!!!!!

As a result of winning the weigh in, my enforced weight loss programme for the bike has begun, off went the stock rear shock and on went the ohlins that was on my perfect keep forever 900ss called duchess, also her carbon SL seat unit. had to find stick on number boards for that as it has a wonderful Foggy #1 in carbon showing through the paint work and i don't want to damage that. I'm really fed up that i could not for the life of me, find anywhere that stocked Fablon in plain yellow. eventually got these motox ones from a place in portsmouth called dirtbikebitz.com
i've also attacked the bike with a drill in an effort to get of excess metalwork, i am using a few probolt bits as well. this weekend i am going to a mates in cowley who is a bit of a wizz with a welder and we will try and convert the pipes from 2-2, into something like ghost has on his bike, sorry phil hope you haven't patented the idea yet and cheers for the insiration.!!
