And that would be correct, unless more modern, your motorcycle whilst twin circuit, those circuits were timed by you the rider, it's highly doubtful most of us would have consistent control over bias and timing to the levels seen in a fairly standard LR MC. Modern m/cs do however. In an LR, we are not trying to lock the rear by applying force to it first are we? If the bias is correct, we couldn't if we tried.

Hi guys
Looking at converting my S2a swb to front disc brakes, was hoping to use the Heystee conversion but the Zeus conversion seems easier to buy due to price and availability so thought i would ask if anyone on here has fitted the Zeus conversion eventually i want to do the rears as well but want to convert the front first

Hi Cornish Rattler, I’ve got a series 2a myself. Brakes are currently poor - was thinking about fitting the zuess kit myself - did you go ahead with the project in the end? Did it make much of a difference?
