kit includes all that is pictured,

piston measurement is 12.50mm width and 37mm length, piston + spring is 74mm.

M10 1.25mm pitch banjo bolt included but if you want 1mm pitch message me and i will change it,

Best to check your master cylinder is correct to this kit before buying, suzuki used master cylinders exactly the same as the ts ones on different bikes these may have larger width piston kits so please check, i have another type of rear master cylinder kit in my ebay.

If you need any more info just send me a message, paypal only, sighed for post included to mainland UK, cheers for looking
