Re: Seem to have mislaid a disc
 

Mmmmm, 2 discs for me, 1 just looks odd - but it's not my bike :-D

Re: Seem to have mislaid a disc
 

:smt115I've got the perfect solution! Stick on a false disc and caliper on one side made of light weight material. You have now saved weight, without loosing the looks


I'm a genius :smt045

Re: Seem to have mislaid a disc
 

No, get another 330 mm disc and furrow tarmac when you stop!

Re: Seem to have mislaid a disc
 

Or... I could attach an old record to the other side, and replace the caliper with a stylus... And fit goldwing speakers in the cockpit! Nailing that retro look.

Re: Seem to have mislaid a disc
 

Perfect!

Re: Seem to have mislaid a disc
 

So I read the experiment is still continuing:o

Can't say I like the look but it's function over form.

Is your radial brake a four pad or two pad item? Cos I was reading in Bike mag that a four pad caliper gives better bite.

Article added as it might be of some interest.

Re: Seem to have mislaid a disc
 

I tell you what, I quite like it. I always think it's a shame to have a nice front wheel that no-one can see for the discs, but then I had the loan of a Bros 400 for a bit and that had lovely interesting wheels:cool:

It's going to be a judgement call on stopping power but I really wouldn't want to be giving up a lot of initial bite or power, but then, I'm pretty heavy on the brakes and quite happy with the power I've got.

It's different, and kinda cool I think. It's probably worth putting my boring hat on for a sec to say if you do get in an accident, most police know enough to realise you should have a 2nd disc. It'd be a shame to give people an excuse to claim you could have stopped to avoid the car pulling out if you hadn't removed half the front braking system. The argument doesn't quite hold water because the one disc and caliper you've got is better than a single SV disc and caliper but you see where I'm going with this....

Re: Seem to have mislaid a disc
 

It looks like you've got a Dymag wheel in the front, so the steering already feels light and flickable. Do you really need to lose any more mass on the front end, even if you think if feels OK on one disc, and wouldn't you rather have all the braking power there if you ever need it?

Re: Seem to have mislaid a disc
 

If you remove the second caliper and just run one on a single disk the way it feels now and the way it will after the change will be significantly different.

At the moment, the movement at the lever produces movement in both calipers. If you take away one caliper you will get twice the movement in the other for the same lever movement.

Yep, it's a consideration. I'd be quite happy to defend that legally if need be though, it's not quite like a chopper with no front discs at all and if need be it could be replicated for testing easily enough. It's got potential to be a hassle, though. If I was to make it permanent, it wouldn't be obvious that there was a bit missing, I'd modift the fork leg etc and blank the wheel. But I'm still not 100% sure I will.

Aye, I'd heard that (and from RobW#70 who told me that the 4-pads can have a ramping-up effect, which I noticed slightly on Scooby Drew's ninja but put down to general setup). These are the 2-pads off a GSXR thou.

Yep, I've removed the other caliper already, it wasn't making a big difference but it was there to feel. The movement in the other caliper was pretty minimal as it naturally had less "bounce"- without the disc in the equation the pads didn't back off much, they never released their grip on the ally blank I'd fitted in place of the disc (for easier refitting of the disc, y'see) But there was definately a difference. TBH I preferred it with both calipers! The master cylinder i have fitted is too much for one disc, for my tastes, and the wasted movement from the other caliper helped offset that.

No particular reason not to, the braking power is still more than good enough for road use- my big concern is that it might fade quickly in more constant use, the weather at the moment has meant I can't do a proper continuous test.

There's still very little initial bite, but for me that's not a big concern, I prefer a very linear braking action without that initial step. Riding home in the snow last week I reckon the first touch was actually better than with the dual 320mm discs. But then, I was already of the opinion that the dual 320mms were overkill, and lacked subtlety- too much bite.

One thing which I'm putting down to the lower gyroscopic force is that it tracks road defects more than normal... Quite offputting that, it's the single worst thing I've come across so far. t's not unsafe, but it's taking some getting used to- sort of like having a skinny tyre on the front.

I've picked up a pair of CBR600RR 310mm discs to try out too, as well as a cheap R6 15mm (or possibly 16mm) Brembo-badged Yamaha part which should work better with the single disc. All cheap bits so I can always sell 'em on.

Glad my silly project is still getting interest :) I shifted the disc and caliper to the other side, which reduces the visual impact a bit. It currently has no mudguard, as it's off the bike for a little repair, and I have to say the front end looks ridiculous :smt090 But the single disc is growing on me, it's more an impact thing. You don't look at a Buell or the KTM concept and think "Not enough discs" after all.
