Race chassis

[crazy man]

You just concentrate on getting that bucket ready for the GP young man. You can't miss another one.

think he heard you about 6 hours ago before you posted this lol. l need to get a bucket made bring back that obsechion l once had

[crazy man]

Most people can't fit on a 125 Size bike.

Everyone wants to put their FXR in an aluminium chassis since Hamish and I did it. Get your own ideas Rich.

l have seen what homer simpson made you lol

[richban]

Nice sounds good they a big chassis tho ae? much like a Honda RS250

Not so bad. My Honda RS250 is a little bit smaller than my FXR. The NSR should be about the same a little longer but not much. Front forks are the same length as the FXR. Not a bad weight at 7kg with clamps and axel. Caster is 1 degree less in the NSR. 23. rather than 24. I am just under 6'2" and not that flexible anymore so should be good. Sitting on the RS250 feels just right so will be trying for the same riding pos with the bucket. Looking for 85kg all up.

Yeah when that thing is done it will be a very smart and fast bike. I am thinking if the rider can man up and get on the gas, it will be hard to beat. hehe

Home built frame at the GP would have been Garry Johnston's GL145 special. I would dig up a picture but not on my laptop.

Seems to handle bloody well and the engine is a weapon. Qualified quite well at the GP from memory.

Thats the one. Yellow frame and white tank / seat. Very cool.

I think the drawings are both NSR250 MC21

The pic is the older MC16

That would be Dads one,

Yep was made out of old chair legs he had lying around, was loosely modeled off his monster s4r.

http://www.flickr.com/photos/dty1/63...7628073869347/ the only picture I have of it.

Started as a gl145, basicaly he just built the new frame around the old backbone one, then chopped the old part of the frame away,
main objective was to join the headstock to the swingarm which after riding I can confirm it is.
I reckon if the condensor wire hadn't broken in the two hour we could of been top 3! It is faster in a straight line than most, handles ok too.

Engine is gl145 with a bit of work done sucking through Mikuni Tm32.

Gl145 forks with emulators in there, swing arm is gl145 with some welding and bracing added to make a new shock pickup for the $70 chinese shock.

carbon fibre or kevlar tank cover and a small homemade tank as well.

Last meet we weighed it in at mid 80s.

Lets just say there are plans in place to build a new frame. wont go into any details but just wait and see!

This has all got me thinking, well dreaming is probably more correct as I have no tools time of money to undertake a project of this type, but what is the best material to construct these frames out of?

I mean obtainable stuff that the normal man could work with.

Plywood, cover sheets are cheap as Bro

im just using ordinary tube steel you find everywere like 1.5mm thick mynes all scrap steel

I dont have much engineering skills at all but just jumped straight into it thought what is there to be lost from giving it a go and its came out good so far, ok its not the best but its my first ever frame I built and limited gear, I really want to get a job as a engineer now and learn to become even better and make a proper jog now know how Im going to do it and make a way better frame which will probably happen but ill get this one going first then worry about another

That laterally (get it, Its a frame joke)

Pick what you want then think of people that use it.
if you want aluminum look to people that make bull bars etc.
If you want light gauge steel look to furniture makers
High grade steel such as chrome-molly stock cars the top guys use it for roll cadges if have seen it on the net in NZ.
Go karts the real ones are possible sources as are push bikes.
Grumph has used steel from an unusual source for a large diameter spine.
thin Alloy pipe think irrigation.
Micro metals are happy to sell alloy by the meter. They sell all sorts of round, sheet, plate, tube, box section and extrusions etc
people who build stock crates mainly now use alloy as well.
Its amazing what is at scrap metal dealers and in scrap bins.
I have a surf board at home that a guy at work had ts broken but it is the start of either a tank male or a Carbon fibre frame.
You can also buy ready made Carbon fibre tube as well its used in push bikes.

You of course can cut up an old motorbike frame as well. But avoid anything Chinese.
Want some pipe bend a lot of guys that do cowsheds ESP rotaries have computer controlled 3 axis benders.
Most of the mufler shops have real flash mandrel benders now.
in fact my area i live in has a foundry an autoclave is over the road. 4 specialist alloy/Stainless fabricators.
Why? it has a tyre shop, factory and we have mining and dairy farming. population 8000.
Beer goes a long way.
