Fitting a pointy rear brake to a curvy

[NedSVS]

I know quite a few people find the rear brake "too good" on the curvy SV650; I have locked the rear more times than I care to remember :!: Suzuki must have realised the problem too, because they reduced the rear disc size from 240mm to 220mm and the caliper from twin opposed pistons to single piston. I have heard of people shortening the rear brake lever to reduce its effectiveness but it usually looks pretty amateur. I have managed to fit the pointy rear brake to my curvy, but it does need some basic engineering skills to do (but I wouldn't put it beyond the skills of a good DIYer). overall it cost me peanuts to do, as I bought the pointy parts I needed on Ebay and then sold my curvy parts back on Ebay. Contact me via the PM system on the forum if you are interested in having a go at this one yourself and I'll explain further. If there is enough interest I will put an information package together (but you will have to give me a little time).

Never had a problem myself. Locked it a couple of times, mainly in the damp or when kicking down through the gears to rapidly, while on the back brake.

Looks like a very tidy conversion though.

It does look good, but do you honestly think the rear brake was too good?

[Stig]

I found that adding a few well placed drops of oil on the rear disk did wonders in making my brakes less effective. :wink:















Please do not try this at home as, although effective, is a mind blowingly stupid thing to do and I did not really do it.

Very neat, well done.

How did you locate the torque lug on the swingarm?

[northwind]

Mmm, I like that...

[NedSVS]

Yes I definately had a problem with the rear brake (either that or my insensative size 11's :lol: ). When you hit the front brake hard the back goes light and makes it all too easy to lock the rear. If you are not a heavy front braker you may not have noticed the problem, but I assure you it is most likely to occur in an emergency stop situation (ie Just when you could do without it :!: ). The torque lug was created by drilling a 10mm hole and putting a 10mm cap head allen screw and nut in. The head of the allen screw is modified with two small flats to suit the size of slot in the torque plate and the nut inside the swingarm has a drop of loctite applied.

In that case I had better swap the engine for a 250cc thats the only thing that locks my back wheel. I love going through the gears (may be too much) :lol: :lol:

You have made a good job on that though fella. :thumbsup:

[northwind]

The thing is though, when your rear is unweighted to the extent that it's hard to use the brakes without locking it, it's also uweighted to the extent that locking it's pretty irrelevant. A lot of people are terrified of sliding the rear because they think it's going to come right round and drop them like a stone, but a rear lock when the weight's right on the nose is nothing to be afraid of. Just let off and reapply.

With your mod, just wandering about the strength of the mod. Is it totaly up to the job or would it be better to use chem metal to hold the bolt to the swing arm. Im not sure of the stresses that it has to endure though.

I may have failed my degree in engineering, but I can assure you I learned enough and am quite confident my mods are up to the job. If I had any doubts I would have left well alone :!:

[Carsick]

I agree, in terms of stresses there doesn't appear to be a problem. I'm just dubious of the necessity.
Most bikers are heavy front brakers. I certainly am and the back slides around like a crazy thing at this time of year. You get used to it.

Personally I think its a good mod! It tidies up the rear end and also provides the rider with a brake system he wanted! who else can say they have done a mod that worked out this way? not many of you, 'I changed my screen'+'I use HH pads' dont count as thats not really engineering a new solution is it? If I had a curvey and was like some of the riders on this forum, for that matter some of the riders not in this forum who have a lot of problem 'feeling' the brake pressure and kept locking it up I would be very excited at the possibility of a solution. Rather than knock this man why not praise him for doing something different?

The only thing I would say to NEDSVS is if its a new idea then perhaps put a disclaimer in the instruction package ;)

all round good idea buddy, nice work :thumbsup:

[Diveboy]

PRather than knock this man why not praise him for doing something different?

Don't think anyone is Knocking him. I think everyone agrees its a good mod and looks very nice. It's just that some of us don't think its a necessary one but that could be said for all mods. For instance I have absolutely no need for a lower seat but I would like handle bar risers.

granted

If I had a curvey and was like some of the riders on this forum, for that matter some of the riders not in this forum who have a lot of problem 'feeling' the brake pressure and kept locking it up I would be very excited at the possibility of a solution I dont have this problem as I can feel the brake so dont need this solution, nor do I have a curvey so perhaps I am not the right person to say this but I have not told this guy it is an unessary mod have I?

and before you say it, yes I have looked through the post and nowhere has anyone actually said it is unecessary, just a few comments stood out at me and I triggered my reaction, as I am not Nedsvs perhaps I should shut up and go away.

[Diveboy]

Not at all I see your point. Its a nice tidy mod and the guy deserves a lot of credit for a job well done. Which to be fair I think he has got.

I tend not to post if I don't like something that has been done as that's the last thing the owner wants to hear. Especially if they have just spent all their savings on a pint job they think is fantastic, post on the forum and I turn round and say that it made me blow chunks on my keyboard :o . I think we should have a constructive comments only posting rule.

Anyway.....

...How much does everyone earn? Where do you live and what's you NI number? :lol: :lol:

[northwind]

See, if I'd done it, I'd have used a CBR600 caliper or one of those teeny tiny Brembos... But it's still very cool.

When I had a gambo I used to put my dap on the wheel to brake.
