Radially Mounted ?

Can anyone shed light on what this new phrase/discovery means? Was just
reading about the new R1 having the same callipers as it's predecessor
"except now they are radially mounted". I would have thought that all or
most callipers were mounted at a fixed radius from the wheel centre so
therefor they must be radially mounted? or does it mean something entirely
different.

Right chaps, sorry to trouble you at this time of night, but there's a
bloke in Britain asking awkward questions. Usual drill, make it look
like an accident. Your plane is waiting outside.

 

Aren't sportsbikes BRILLIANT. You get radial calipers, more power than you
can shake a stick , consumables that cost a months wages...
Brilliant!

Phwoar!

I'd rather keep a sportsbike than a wife. I found wives more expensive
in the short term and certainly in the long term.

 

I need to know why. In 20yrs time my SOB's gonna be an R1. Will it affect
my Zimmer frame mounts?

The real advantage is a much stiffer mounting for the caliper. Most calipers
are mounted with two bolts clost to the top of the caliper so the caliper
sort of "hangs" from the mounts. In severe use such as racing the caliper
can vibrate and flex. Radially mounted calipers are secured top and bottom
in a very robust manner.
Only an all-out racer would notice the difference when brakes are used to
their absolute maximum.

Yeah yeah but I reckon my new AP Braking disks and callipers will be better

Paradoxically the calipers on my Beemer are considerably more awesome
though.

Seen this yet Champ? www.apracing.com/motorcycle/dbmc.htm
Get yer wad out boy....

Ahaa so that's how it works, seems fairly self explanatory now Ive seen the
picture, prob makes for easier mainenance too.

Although it was failure due to fuckwittedness.

It nearly happened on the last 350LC. Entirely due to my own
fuckwittedness.

I fitted braided lines, one down to the right caliper, and a cross-over
from there to the left. What I didn't allow for was the horn sitting
where it did. When I hit the brakes hard, as I am prone to doing, the
brake line would loop over the top edge of the horn and snag
momentarily. I realised this when I looked down inside the fairing to
see what was making this strange noise and feeling when I let off the
brakes. It struck me that had I carried on, the brake line would have
ripped out of the fitting and I'd have been sans brakes from then on.

I had to stop and bend the horn bracket right up out of the way to get
me home, and then fit some proper p-clips in the mudguard mounts to hold
the brake line down.

 

I can confirm that a Bike is cheaper than a wife, which initself is cheaper
than keeping a wife and an ex-wife. However having kids beats the lot. ;-)

ah - I am *enlightened* oh wise one.

I always thought that Radially mounted brakes meant more unsprung weight
which was a *bad* thing.

Sure I'm happy - but is it any use?
