Quite good money, they're hard to get hold of here as some un-named South Australian and NSW gents use them with dodgy replica backing plates and have got them thru on P3 Hondas as a sort of replica. I have one in my roadracer but I'd have thought it'd be a bit heavy for a 125 Mick. Bloody good brake when well set up, though... :o

The Buzuki GT750 brake doesn't pass muster everywhere, like in UNZUD where it falls in the no Jap parts basket.

Menani magnesium is my $$$$LS wet dream, though my Triton has to be happy with 2LS Norton for now, which is OK that set up stopped a lot of Manx's.

Yes Glenn. It is all new and foreign to me the P4 125 thing, and what is best. Got a bit of advise from Lozza earlier in the piece Glenn. Matcho Mick, has been giving me some good guidance. I am looking for a Grimeca 180mm Quad hub only. I have two complete backing plates.

Yes some beautiful hardware there Marc.

Click on the picture of this one to check the price out, make sure your sitting down first though.

Don't faint, but I have a 180mm 4LS hub only, but have no idea if it's a Grimeca... don't know of any others available in 180mm though. PM me yr email address, and I'll send you a couple of pics.

Cheers GD  ;)

If any of you gentlemen are looking for a Suzuki 4ls drum I have one. But I want $600 for it. On drums for racing smaller capacity bikes the 2ls from the CB 72/77 or CB 450 is a good drum. I use one on my P5 500 yamaha. They are also P4 correct. Curly
