Wave brakes for VTR250?

[humphrt]

Hey there,

i was wondering if anyone knew what new(ish) sports bikes which you can get wave discs for had 296mm disc size? I was originally going to fit a twin disc set-up from a CBR250RR but figured why add extra weight. And of course nobody makes wave discs for a VTR250 so i was wondering what bikes parts may be interchangeable.

Could you post your disk dimensions up? Total Diameter, Carrier Diameter, Disk Diameter (this one doesn't really mater, you can make an adapter for more meat), Number of Mounting Bolt Holes, Diameter Between Bolt holes (center to center)

Is it full floating?

According to my brake catalogue the only other bike that shares that same disc is the 250 Hornet.

Sorry im new to motorbikes. How do i measure this stuff?

If there arnt any discs which match perfectly diameter-wise then is it possible to fit different sized discs?

ive been told hornets and vtr disk size is the same not to sure on that so don't quote me.

I want a twin disk set up I don't like the brakes on my bike compared to other bikes I have ridden, Any one no the exact effect braided lines would have on them?

[humphrt]

Yeah but you can't get wave discs for a Honda Hornet 250 or VTR250 because they are the same discs.

If you want to got with a twin disc set-up then steal the front wheel off a CBR250RR and a second caliper. But then you are adding weight which is why i'm trying to get the same effect while reducing the weight by adding a wave disc and braided line and sintered pads.

if you want to save weight stop eating pies....MMMMMMMMMpies

Yyyyyyyeah. Tell me again why you want them? Have you considered braided lines?

I wanna stop faster(without the use of a brick wall).
How much difference does braided lines make?

Will wavy discs help that? I thought it was just for looks?

Replacing standard rubber lines with braided lines reduces that classic `hydraulic-y' feel of hydraulic disc brakes. You know, that spongy disconnected feel. Cable drums are much nicer in feel, but apparently they're no good

Braided lines improve the feel and make your WoFs living hell :P

Wavy disc actually dissipate heat in a more efficient manner than round ones and much less likely to warp when they are hot like the garden variety round ones, but if you're braking hard enough to do that on the road you really need to check your style.

The braided line thing can be a hassle if you don't use the factory made dot approved ones, the bikeshops should only sell you the right things if you say it's for a roadbike.

My suggestion humphrt is that you first get the calipers serviced so you know they not holding back the brake pistons then you experiment with different pads once you get the braided lines, sometimes this can be all it takes to get a really good increase in braking performance.

[humphrt]

Wicked, thanks for the advise guys.


Now off topic, how do you harden suspension, does it just need a service too? It just seems a little spongy for a "sports"bike.

[imdying]

Just change the feel.

Good advice (no offence to any fatties reading this)

Won't stop you faster... unless you're more confident in applying the brakes because of teh change in feel.

Yep, just for looks.

Yep, can do, although new oem rubber lines feel very similar, as do the low expansion rubber ones.

Improve, that's subjective. I prefer the feel of a rubber line to a braided line, YMMV.

Not true.

But this is. Service the brakes, I would put money on the fact that they're neglected. Strip and rebuild the caliper, new pads, fresh fluid, will make a world of difference.

/edit: You should add some more information to your profile (age etc), somebody might offer to help you service your braking system if they've some idea of who they'd be dealing with.

i can concur with imdying about braided lines i personally don't like them either

I have made low expansion rubber hoses made up by local brake/clutch store.

Brake lines should be replaced every 4-5 years according to manual anyway.

As long as people dont automatically say oh look he's only 21 he cant be a real biker he'll only be a hoon

That seems to be the general reception that alot of us youngn's recieve, not saying thats what your doing but whether by our own fault or not its wat seems to happen.

Notice im trying to get the brakes/suspension working properly not build a turbocharged/nitrous/boyracer heap of s**t
