SV650 caliper on a GT500 front end

[Willsy69]

Hi
I’m looking to fit an SV650 caliper onto the GT500 front end of my new project. Has anyone carried out this modification and has a drawing or a cad file I can use to get a conversion plate made?
Cheers
Colin

Lots of links here - https://www.kettleclinic.co.uk/kcforum/ ... 85#p109885
and here - https://www.kettleclinic.co.uk/kcforum/ ... 50#p106028 .
I upgraded the brakes on one of my my GT550A with chinese m/c's with twin front discs + a hydraulic clutch - and a GS1000 m/c + GS1000 calipers on my GT750B.

Lots of options for a straight swap as the SV650 calipers need some work to fit the GT forks.

Twin piston calipers are a popular upgrade for early Suzuki GS bikes.

The early commonly-used caliper has pistons of different sizes.
A member of the Suzuki GS forum sold an adapter plate that allows for easy upgrade for GS & GT Suzukis.
The upgrade kit requires the use of a slightly larger brake disc.

I used that adapter for my T500 cafe build. Also did a fork upgrade & switched to an 18” rim.
See my T500 build topic:

It turned out quite nice.
But the availability of good used calipers was becoming problematic, so they designed a new adapter that works with the newer calipers with pistons of the same size.

So looking into GS upgrades is the place to start.
