opinions is there much of a difference / advantage going radial ? I am doing a USD conversion and I can sue 929/954 forks or cbr1000rr forks

both same price roughly minus callipers , do I spend an extra £1-200 for the radial setup or just go conventional 4 pot nissins?

Personally I'd go for the most modern possible for a few quid extra. Radial calipers don't give massively more power but they do have easier tolerances and less flex meaning that a bit more potential can be extracted from them.

I doubt you'd notice the difference between braking systems, but you might notice a superior front fork setup. My guess is that the later forks will have superior internals, but I might be wrong about that.

to be fair there isnt any real advantages of having radial calipers, may be the ability to go to larger discs is a little easier, possibly a bit better pad wear, and of course the way they look,

they certainly don't brake £200 worth better,
me, i'd stick with a good old set of nissin 4 pots, rebuild parts are cheap, you'd probably be able to buy a couple of sets for the same price as a radial set,


just my opinion of course, jump on the band wagon if you like the look of them, if you don't care, then just get the regular brakes,

Id stick with the 4 pots, or chuck the extra £200 towards some pretech callipers Drooling

I want Usd forks the brake side of it doesn't bother me tbh just if the radials offered a performance increase id would spend that .never had radial and tbh the 4 pot sp1 nissins I have on there atm are more than ample for the weight of the 600 and will go on the blade forks also

Hi

Not sure there is any real advantage in radial calipers. I can't see how they are actually lighter (when you include the extra weight of the mount), more rigid or usefully more rigidly mounted. They do have the advantage that you can swap around very simple spacers if using different sizes of disk.

Most are 1 piece calipers which will likely be more rigid (but there are 1 piece conventional calipers) at the expense of being more of a pain to strip down.

So, can't say it would bother me if they are both decent forks and calieprs. But given a choice between (say) some forks with radial calipers and some forks with some of the 6 pots fitted to the 'busa, etc, there would be no contest.

All the best

Keith

Rather given the choice between poor brakes (with regular required maintenance) like the 6 pots used on the 'busa, etc, and an alternative (whether radial or not) I wouldn't touch the first ones!

All the best

Why USD conversion?

Presumably for cosmetic value.

Thus is the aesthetic of radial worth it for you?

Given the choice, I'd go for Yamaha sports bike brakes, as they always seem to be the sharpest.

Sumito calipers based on the ISR design? (Aka those ones with the big star bolts on the back).

954/929 calipers are awesome, I found Brembo goldline calipers to be a bit sharper on the road (Mille front end possible?), but not by much. Radials are ok, not a night and day difference to be honest.

Yep; those.
I was never that impressed by the Brembos - they aren't bad, but I wouldn't consider them good either. Did seem fairly compact however, think they may have been a bit lighter at least.

Can you find a truly shit 4pot or 6pot caliper these days? Despite being slated to buggery the 6pot Tokico's that have all the issues, are a good brake when in perfect condition.

They are 'ok' when in perfect condition, but still a bit squidgy (even with braided hoses), I would say.
I did keep mine in good nick and never really had any problems - but given the choice, I wouldn't choose them.
Some that felt less good certainly added to the 'excitement' when doing a top speed run on the 2 mile strip at Elvington on someone else's Busa!

Can't see how they'd feel squidgy with or without braided hoses unless the fluid needs changing.

Odd effects from corrosion build up and seals ageing.

All the best

Compared to Yamaha blue spots, both on bikes <2 years old with low miles, the Tokicos were significantly less sharp.
Same after both were serviced, still at low miles.
Bad design, I would suggest; come forward a few years and a popular mod for the GSXR1000 K5/K6 is to swap to Yamaha brakes from Tokico for the same reason.
Suzuki eventually moved to Brembo 'monoblocks' on the 1000 because Tokico just didn't cut it I expect.
