I have noticed that people frequently choose the GSX-R front end for a front end conversion on old bikes to improve handling and comfort. The GSX-R was produced from 1985 through the present, and I'm assuming front ends went through major changes as technology improved. I have found various pieces of information scattered all over, but I can't find what changed on which year, and what those improvements would mean for someone choosing a front end. Can someone list which changes were done in which year, to assist modifiers in selecting an improvement that is appropriate?
Upside down forks where added to the GSXR11 and 750 on the L model in 1990. There are lots of subtle differences and changes since then, and modern stuff is significantly more advanced. Suggest you try and Google part numbers.
