I'm putting a disc brake on my 1978 Pen/KTM, I,m using 35mm Marzocchi forks and have a early KTM wheel with a disc. I thing it was from a 1985 ?? 300. The brake disc has 6 buttons and all or missing. Do they have a replacement disc without the buttoms, I'm just not sure, age I think, but though they did away with the buttns. If not I need to find some buttons. Dave
I think I bought some from Andre at enduroklassiker some time back. Try his site. I Don't have any trouble with the play that the buttons give and they have used this system on recent bikes I think so you might even be able to get them from KTM. Disc brake in 85 is still not a great advancement on the drum in my opinion. Not sure if there is a replacement disc to fit the hub without the buttons.Cheers Bill
Thanks Bill, thinking about making them as I found a good one to make from. Dave
