I'm thinking about gearing -- sprocket specialists only lists having front sprockets for senda -- will these work on my gpr50... thansk

Same engine, same sprocket...just a different # of teeth, but you can order with however many you like. You can pull it up on this application chart here; http://www.jtsprockets.com/52.0.html?&L=0 Look under Derbi road bikes up to 99cc.

thanks -- because i'm old and can't seem to remember to ask both parts of 2 part questions -- here's part 2:
what's the best way to get a derbi front spocket to work for a 415 chain... can jt or ss or * make such sprockets -- or do i need to get one machined locally?

reply to myself:
neither jt nor ss make custom counter sprockets. However, my local machine shop can thin out the 420 sprocket.
