J Juan bought AJP a couple of years ago or so. Basically the new stuff comes with the moniker J Juan. The caliper that's fitted on the newer bikes appears to be a four piston unit. I got one with the
2012 bike, but outside of a very short test ride I never used it, and I didn't have the time to even look it over. Is it as good as the 125 2T/Metrakit version? Hard to say. The 125 2T/Metrakit caliper looks better, and works great with a Brembo RCS 14 master. ¯\_(ツ)_/¯
Getting Öhlins on these bikes isn't as easy as on other bikes. Öhlins has never seemed to recognize any production Derbi, and as far as I know they haven't done so with the 50cc versions of the Aprilias. But for creative people that doesn't mean you can't get the job done. On the
DRP 2005 bike I did such a thing. However, that solution wont work on the later bikes because there's no place for the reservoir.
While doing research for the
2012 bike I was able to get the specs for the rear shock. I even found an Öhlins dealer that was open to assembling a custom shock for me. But I ran out of time before I had to head off to Japan for the
Adventure. Because I didn't get everything together I don't think I've posted about it yet. Still this is something for which I still intend to follow up on once my finances get turned around.
