Posted November 14, 201311 yr the fzr forks that I m using run a twin caliper setup an it weighs a tonne I d like to remove the calipers an fit just one that is smaller an lighter what other yamahas have calipers that have holes that are 100mm centre to centre? I ve tried a dt caliper but the spacing is 80mm
November 14, 201311 yr Moderator I made my own plate for the tracker. fab it using ply or whatever and copy onto 6mm dural and use a hacksaw and drill. simples
November 15, 201311 yr Moderator Do they have blue or gold spot calipers from the R1 etc fitted they are 100 m spacing , if yo wanna know the weight of 1 i can weigh on for ya , i have on e on the TDR
November 15, 201311 yr Author I made my own plate for the tracker. fab it using ply or whatever and copy onto 6mm dural and use a hacksaw and drill. simples don't think I can make one from some plate the dt caliper is 80mm so it would be 10mm longer at each end when the m6 hole is drilled there would only be 2mm each side of the hole can you put a pic up yours drewpy?

I didn't say i have the same bike, just how to make a bracket click on the xs400 link in the sig, shows how I did it
November 16, 201311 yr Author this is my current calipers http://img11.imageshack.us/img11/455/6t0n.jpg Uploaded with ImageShack.us
November 16, 201311 yr Moderator that looks a lot like the original TDR caliper did a blue spot minus pads but with all pins springs etc is 755 grams and should go straight on there
November 16, 201311 yr Author just found my caliper on ebay seems to be from an fj1200 those blue spots work as a pair don't they if I fit one the master cylinder will push too much fluid in / not enough if I fit a smaller mc ?
November 16, 201311 yr Moderator its to do with the bore size of the master cyl. smaller bore less fluid pushed but a softer brake and may pull to handle bars larger bore, more fluid but harder feel
November 17, 201311 yr Virtually all big yams (600+cc) made after the mid 90s have calipers with 100mm spacing, apart from stuff with radial calipers. Beware that yam changed the master cylinder size around 98 for new models and if you put blue spots, gold spots, silver spots on you need to change the master cylinder too or it is as wooden as hell.
November 17, 201311 yr Author its to do with the bore size of the master cyl. smaller bore less fluid pushed but a softer brake and may pull to handle bars larger bore, more fluid but harder feel what I meant was the blue spots are a twin caliper setup so they have a big enough master cylinder to feed both calipers I d like to fit just one caliper theres no need for a twin setup on this bike if I fitted a blue spot caliper with its intended master cylinder then suely the mc would push too much fluid as its designed to work with two calipers

February 16, 201411 yr Author 4 pot calipers have 100mm spacing 2 pot have 75mm or so it seems I cant find a 2 pot in 100mm spacing
February 17, 201411 yr Moderator 4 pot calipers have 100mm spacing 2 pot have 75mm or so it seems I cant find a 2 pot in 100mm spacing your reading to much into it, get a four pot and match the mc to it. It'll work wether you use 1 caliper or 2 either side. Match up the MC bore, TDR's MC bore size will work as it uses 1 caliper. why not go the whole hog and use the disk too
February 18, 201411 yr Author I wanted to replace the heavy 4 pot with a nice light 2 pot caliper The bikes only a 125 there is no need for 4 pot caliper s Is it possible to get 2 pots with 100 mm spacing
February 18, 201411 yr Moderator I have get a 2 pot caliper in the garage from a suzi 125. I'll have a look but doubt it would be what you wanted. you can never have too much front brake
February 18, 201411 yr Author Thanks drewpy I ve found 2pots from 5o mm to 75 mm but none in 100 mm yet
