Showa BPF 43mm into the RC51

Hi all,

First proper post and I'm hoping someone maybe able to give advice or help. I understand that the standard fork is Showa 43mm and I have available to me at a great price, a set of big piston forks from a GSXR1000 2010. I'm thinking of swapping them in and using some M4 Brembo's. I'm guessing the newer fork technology would be better...

Any thoughts or experience in doing something like this?

Thanks

Jay

have a look at the fork length. the 51 uses a pretty long fork. you may have to extend the suzuki ones. and also consider axle, spacers, rotor spacing possibly etc

Swapping one stock fork to another one is just silly. OEM forks are all built to a price point by a boardroom full of suits that decide what parts ultimately end up on the bike not the engineers or test riders. If it costs too much it gets replaced, if it has to much adjustability that get could the average rider in trouble if they dial in the wrong settings it gets replaced so no matter how good the technology is it is still going to suck compared to having a proper aftermarket cartridge kit installed into the forks regardless of whether they are 20 year old OEM RC51 forks or brand new latest & greatest gas charged forks on the 2016 Kawi ZX-10R.

A lot of people in the sportbike crowd simply cannot get over the basic idea that just because it is different, it does not make it better. I see people swapping one OEM master cylinder for a different OEM master cylinder or swapping OEM RC51 brake calipers which are some of the best axial mount calipers ever fitted to a production bike out for some crapass OEM radial calipers off a CBR1000RR or GSXR etc and just shake my head in disbelief... If you want to improve the performance of the bike then you have to step up past OEM parts to get there.

Ok guys, my thinking was that 10 years of development by the manufacturers means technology doesn't stand still. The BPF forks are known to be very good indeed and the original RC forks, although good are now getting old. It was just a thought.. Maybe I will get the Kyle Ohlins 30mm conversion instead then.. Oh wait..

I would have some Ohlins forks if I could find some for sale.

I agree in most cases. Now swapping SP1 calipers and master on the old 900RR IS a cheap and worthwhile OEM upgrade.
