front rotors

[bud7680]

:ummm:Can I put (YR.)2000 rotors on my 1988 and get improved braking?

Are they direct bolt on?

Will I need different calipers?

Found both left and right rotors for 30$/pc..

What is the process if it can be done? Trying not to spend too much for end result of improved braking and better rotors!

The late model rotors are too big to be mounted without caliper adapters. They will bolt onto the wheels, but the calipers won't line back up with their mounting holes on the forks. Sean Morley sells adapters that allow the use of Hayabusa calipers that folks here have had great success with. With those calipers and adapters you would be good to go with the larger rotors.

+1 to Jim's comments.
They will bolt right on. There are a few others that fit too.
Need caliper adapters at a minimum though. Adapters for the OEM calipers are hard to come by and expensive.
You can scan ebay for a set of gen 1 busa calipers and then buy the busa adapters from Sean Morley. Its cheaper to go this route and it will dramatically improve your brakes.

I got my OEM caliper adpters from Sean. they were made by Jedi. Then Sean had them chromed for me. They weren't cheap, but you get what you pay for.

By the way and trying not to hijack the thread i add something else. Im running aftermarket 320mm with offset on Dymag wheels on Grizzly and now i'll be replacing the front rim by a taylormade that has bolt pattern for vmax (132ID, 150BP). I found a set of rotors that uses the same bolt pattern has the vmax and bigger rotors (320mm), that is YZF R7 (99-02) and FJR1300ABS. It was a PITA to find them but they do exist if someone wants to go to the limit... Im ordering mine... Cheers

Since you have an early bike you'll need adapters either way. The 93-up forks will accept R1 calipers as a direct bolt on replacement, no adapters needed, but since your forks were designed for the smaller rotors they won't fit.

The 'busa caliper/adapter combo I think would be your best bet.

You can find chinese "wave" rotors (for that trick look) on ebay for fairly cheap that people here have had good luck with, but the "new" style OEMs are perfectly fine as well.

I'm not sure what/if the benefit is to the wave rotors. I rode a snowmobile once someone had swapped a wave rotor into and it felt like ABS was running all the time when you use the brake, I dunno if it's supposed to be a crude form of antilock or what. :confused2:

I'm not sure what/if the benefit is to the wave rotors.

More leading edge for the pads to "bite" onto. Its the same concept as the holes for the additional grip, you just get more from the usual "wave" pattern.

My suggestion is to either spring for a new front end from a sportbike but that can get expensive, or:

If you just put-on the '93+ 43 mm VMax front end, you can use FZR1K or YZF1K front calipers w/the stock 298 mm '93+ rotors. You re-use your stock wheel & speedo drive, your fork brace/fender, it's just the tubes/sliders & triple-trees from the '93+ you need. Most people here would suggest cartridge emulators and/or a Progressive Suspensions fork spring kit to go w/it, but you can always go 1-at-a-time after installing the 43 mm VMax front forks & 4 pot brakes.

As noted. You would be very impressed with the stopping power our 6 piston conversion gives. Far better then the R1 bolt on calipers for the later models. We have made a 320mm conversion for both years and even let it use a single rotor and 6 piston caliper. BUT, I haven't made any mass produced versions of those yet.

[bud7680]

I thought if all that was done the master cylinder had to be changed as well and on and on and on.....

I gather though that with the newer rotors I would at least need the adapter bracket from Sean to re-mount stock calipers. then I could update to braided lines and better calipers later.

Am I right or not?

Thanks for all the info. so far though,prolly not done yet!!:clapping:

 

[bud7680]

oh yea, how much are the adapters?

Can't I just paint them black or silver with a rattle can?

I will have a R-1 conversion with adapters for sale here in the near future.

The busa adapters are $50. You won't be able to use them until you get the hayabusa 6 piston calipers. The adapters that allow the stock 2 pison calipers to be relocated run $80 Raw (though I have had the ones on hand coated which is $10 more). I also have adapters to use GSXR 4 piston calipers with the smaller rotors (though this is an improvement it's not like the other adapters provide).

What years of busa calipers am I looking for?

Master cylinder(stock) still useable?

Will this set up (used on an 89) require a change to larger late model rotors?

Steve

The adapters for busa calipers require the larger rotors
The adapters for the late OEM calipers require the larger rotors
The adapters for the GSXR calipers can be used with the early rotors

 

[wildweasel_pt]

The Busa rotors/6 pot calipers are the gen1 Busa (320mm) but people use them with the 298mm post '93 vmax rotors instead of the prior '93 282mm rotors (same as rear all years).
Best option is go for Busa 6 pot calipers with 298mm rotors and adapters for the 41mm forks (can get that from Sean or from ebay if he doesn't have rotors and calipers in stock). Be careful not to bend the forks though with so much stopping power... lol

I don't know if the early front end & adapters is the "best option." Not to me. Locating a 43 mm '93+ triple trees & downtubes/sliders allows you to use the stock front wheel. eliminates speedo problems, allows mounting all stock accessories where they belong, i.e., handlebars, headlight, speedo, turn signals, brake splitter, fender, femder & fork brace... . About the only thing you have to do is get the '93+ 298 mm rotors and make sure your new calipers will fit. The 100 mm caliper spacing of the '93+ brakes allows a variety of calipers to be used, and if you want to keep it in the family, you can use 1000 cc FZR/YZF/R1 calipers, although for some of those calipers you may need the 320 mm rotors. The 1994 FZR1000 used a 6 pot caliper. No adapter needed. With a set of HH pads & s.s. brake lines, you have an upgrade which will cost far less than going with an USD sportbike front end. You could do the whole thing in a 2-3 hr. period if you already had good steering head bearings and didn't have to fit new ones. You don't have to use 'slugs' on the sportbike downtubes and since it's a 'remove & replace' effort, the average guy can do it in their carport and have the bike done in an afternoon, no machinists, no adapters, no expensive parts sourcing, and if you want, it can even be all-Yamaha.

If all you want to do is change calipers/rotors, then yes, the adapters for the early front end will save you a bit of dosh, as our Brit friends like to say.

Sure there's more than one way to do this, and that's the beauty of this bike isn't it? You can choose a path, easy or difficult, inexpensive or $$$, and arrive at a similar place. Any way you go, it's better than the stock pre-'93 front end, if you go to the '93+ front end at a minimum. In my opinion, spending $ on the '92-earlier front end just isn't worth the $, not when you can upgrade so easily. Just shop the parts sources, buy stuff on-sale/used, and when you have the parts acquisition completed, a few hours will result in a big change in the bike's road performance.

+ ! Some of us sell parts cheaper than others. I like to pass the savings on to others when I can altough I cant give stuff away I will help you when I can. I have a late model front end here with progressive springs that only needs fork seas l that I can fix you up with. I can do the seals & send them to you good to go or walk you thru doing them your self.Fell free yo call me at 813-270-0000 or email me at [email protected]
