Got a pair of 4-pot RVF400 calipers here that you missed nicking the other night in what looks like very good condition...

Easy. Fit another one as well

Sounds good but what caliper are you using? K4pot?

It sounds like upgrading the caliper may be a better long term option.
WHere can I get a 2nd hand caliper from? Kane has older ones but not new ones. Is there another BMW 2nd hand parts dealer in NZ or are people getting them from ebay overseas?

the caliper i have now is the big std brembo,but i have got a pair of nissin calipers of trade me.They arent the usual suzuki ones but of an Honda

OK guys I'm having a hard time getting my head around the replacing caliper thing so apologies for being thick but can I get help with the basics.

For those that have replaced their single front stock caliper -

1. how did you know what ones to get? I've been trolling thru the BMW sites & a lot have got later model K100 4 pot LHS callipers to replace the stockers with.
If you have done this- where did you get your Kseries callipers from? Trademe? a BM wrecker in NZ? Off Ebay overseas? New from an overseas supplier?

2. Some have got new blingy billet heavy duty systems worth a lot of money- nice but not on my agenda.

3. Some have replaced stockers with another brand/ from another bike. How did you work this out? Are the mounting holes the main consideration? I'm not really interested in spacers, excessive machining & offset calculations etc at this stage. Later on I may look at it along with different forks etc but for now getting it going is the main motivation.

I have found what appears to be standard 48mm pistons for brembo brakes however noone can verify they are the same as what came out of my calliper - hence my hesitation to do the easiest thing & buy them. If they're $80nz & a better caliper is not a lot more, It'd be better economically to get the better caliper if you get it.

Many thanks in advance.

PATAGONIA EXPLORER: Argentina & Chile
18 days: 13 Nov - 30 Nov FULL / 3 Dec - 20 Dec FULL

Patagonia, a world of vast blue skies, deep blue glaciers and towering snow capped peaks. A motorcycle tour through this region will be some of the greatest biking moments of your life. This motorcycle tour is a scenic overload, beginning in the Chilean Lakes district town of Pucon we ride into Argentina and onto Bariloche, via the famous seven lake ride, every inch is a scenic splendour. Further south we enter the vast and remote Patagonia stopping overnight at a, still working, Estancia before riding into more sensational scenery as we hit the Andes at El Chalten. No tour to this region should miss the incredible Moreno Glacier, we ride our bikes out to this staggeringly beautiful part of Patagonia before riding into Torres Del Paine National Park. This place will leave you awe struck and we dare to say that it is possibly the most scenic motorcycle ride in the world. This is an incredible motorcycle tour through some of the most amazing landscapes, most remote regions and most mythical areas in the world, no wonder its our top selling tour.

Thats the one I did, Got all my info about what caliper was required etc off this thread. Download the CAD drawing and take it into an engineer and they can make the bracket straight off the drawing, it contains everything the engineer needs to know. Others had already done all the investigation so it was easy.

It's not just about the mount spacing, the caliper must line up and provide appropriate coverage of the disc as well.

I sourced my RF900 caliper off Trade me from a wrecker in Chch.
