Fork Swap 09+ BPF into 05 1K

Nope.....they put what's cost effective to put in there. Street guys don't care and racers rip it out anyway.


Look at the latest bunch bikes out now. Nearly every Japanese bike (aside from Yamaha) now comes with Showa BPF front forks.

09 and later GSXR-1000, 11 and later GSXR-600/750
11 and later ZX-10, 09 and later ZX-6
12 and later CBR-1000, 13 and later CBR-600

All of these bikes now have BPF forks. Why? It's not that great of a design, its difficult to swap fork springs because the spring is buried at the bottom of the fork, VERY impractical for racer. Pretty much anyone that races any of these bikes would be ripping the internals out.

So why?.....because apparently its a cheap (inexpensive) design. Go figure.

Except for the HP4. Active Sachs suspension front and rear.

The HP4 is not a Japanese bike, it's German. There's still plenty of EU bikes that are not on Japanese suspension of course. I was just referring to the BIG-4.



.....actually there's several Italian bikes that come with Showa suspension (not BPF).

For anyone interested thought I might post up I got a new front end from a 2011 600 w/ BPF cheap and fitted it to my 01 1000, took a bit of work to get the bike setup right but came out nice.

Think everyone is right, not worth it for the forks so far, comparable to my well setup 01 forks, brakes on the other hand are 10 times better than my old 01 brakes so it turned out good...
