Race chassis

Yeah the MTB brakes work great as a rear brake, however will only last a lap before they over heat if you try and do skids into the turns...

My effort was really half arsed and it will be getting rebuilt soon to make it looks nicer and be lighter! I gotta shave a supercharger worth of weight off the bike haha

Yeah that worked well for sure. I still have 2 sets in the shed. I would trial the cable version. I will be almost as grunty and no tiny volume of fluid to cook. Will get around to doing one myself at some stage.

It's lighter than the MB.....

So Glen What bore and stroke are you going to be running i have a Short stroke 95cc here 54mmX41.4mm
(the stud spacing is different than the bigger than 110 motors though, fixable) but it would end up with real low comp with a flat top with the large chamber head and the short stroke.

The KTM50 caliper set ups may actually be a better bet for any sort of durability as the MX 50 being Auto get a work out.
But if the lack of fluid is an issue it should be a problem to increase that.
Shit after the awesome supercharger effort, i am surprised you are not milling you own billet brakes.

Ha! I was looking at a thumb rear brake in the weekend. He'd modified the foot master cylinder by putting a sleeve in the reservoir (integrated) else the window gets blown out. (Retains foot brake, you feel pulsing through both). He had a Recluse auto clutch on his KTM, & going down snotty hills with legs flailing you need some rear brake. I've been fantasising about a rear brake for my GasGas just as I like to ride the brake a bit exiting greasy left handers as a variable traction control & it would be nice to do it on right handers & probably be more controllable that through MX boots.

But this setup has an AP MC which wouldn't be cheap & its reverse action to most with a pull??

So the set up on the KTM the plastic blows out because the foot pedal presurises the thumb brake cylinder as well?
You also mentioned the reckluse yeah always wanted to give one a go.
I see somewhere they do a manual/auto combined one now. best of both worlds BBR do one for the KLX110 too i think. plus the crf110 has something different too supposedly (but still semi)

Back to the Buckets, or rather tangenting off to my dirtbike; I want to be able to retain the std fittings as it will be piggybacked onto the original banjo fittings.

So really, why would they make a 'reverse' cable pulled m/c?

Not sure... what you mean Dave?
Are you meaning the Kart cylinder?



I seen some combined front brake clutch control one lever someone was selling on TM
I am f'ed if i understand it and i checked and it wasn't even April tried to figure how it stil allowed slip guess it was a initial travel thing then after i posted this i got around to following the links....

The CLAKE is a combined clutch and rear brake actuator designed to free the riders right foot to afford them better control over their motorcycle or A.T.V. To many people the concept of combining these two controls appears strange but you must consider that both the clutch and the rear brake are actually controlling the same thing, rear wheel rotational speed

Bloody clever
Patent pending I wonder how long it is before he is ripped off.....

Interesting idea, but not what I want.

I want to be able to apply the brake whilst accelerating as a traction control. I already use the rear brake like this, but only on lefts of course & it isn't precise enough.

The rear brake foot reservoir glass blows out from pressure of the hand brake, so you put a sleeve in to 'remove' the reservoir.

Brake for traction control .....I guess we are back on the offroader?

It sure is an interesting idea, but as you say. the only problem is you can have initial movement clutch slip or initial clutch lever movement rear brake where as when brain and feet and hands are working you can have either/both.
Still if you add a rekcluse the manual anti stall version...mmmm....
I wonder if it something could be done with a push pull set up so the clucth lever could be set up for
Traditional pull in for clutch.
Push out with fingers for rear brake, That way one lever in correct position for both?
That way, it would free up my thumb for the airshifter

Sunday Monocoque.

If Mclaren were to build a motorbike chassis in the early 70's i guess it would look exactly like this.

Beause that 's what they did

[cotswold]

Not the best quality photo but there are any number of chassis out there

The line up was Donington 1988....125 National....
Kris Galatowicz, Ian McConnachie, Steve Mason, Mark Carkeek, Michael McGarrity, Garry Dickinson, Paddy Corrigan, Chris Palmer, Andy Cooper, Rob Blow, Barrie Irons, Steve Clark, Dave Parman, Kevin Coghlan, Tim Coopey, John Cresswell, Martin Bartlett, Ken Donaldson, Morris McCarlie, Simon Westwood, Tony Flinton, Dean Hodgson, Pete Banks, Charlie Morgan, Les Judkins, Dave Moffitt, Dave Brown & Steve Patrickson.

Evolution ....... Can't wait to see whats available in the next 100 years

[F5 Dave]

Petrol still hopefully. . .not that I'll care by then.

Sunday Monocoque

OK might not be exactly a monocoque, but it is Sunday.
Note the tank is actually part of the frame.

[chrisc]

I know the MJ works build has been posted in this thread already but here is another which I found through them: Aretz Racing. Unfortunately in dutch but nice pictures regardless

I'm particularly unbusy at work at the moment, if anyone has any interesting articles on race bikes/chassis' I would be very keen for a read.

Cheers

Land of the ugly tailpiece.

[F5 Dave]

Oh my, I couldn't watch the rest. Those french know a thing or two about ugly cars & it spills over. The picnic table was just the start, then the ugly duckling duck tail tailpeice.
