Xsr700 to r7

I do not believe so. But it would be impressive to see it happen. You would have to change the bars to drop them down to the sport bike stance. The suspension has USD forks as well so you would have to look into that. Then figure out how to get all of the fairings to line up. The chassis is very different from the R7 but its closer to the MT-07 and I do believe that they used the MT-07 chassis and tweaked it to get that super sport shape but if you are willing to put in the time and effort I think it could be done.

The tabs that hold the upper fairing stay would need to be fabricated and welded on. Probably other tabs as well. Better off buying an R7 frame with tabs exactly where needed and factory painted. Either way, it would be far more cost effective to just do a trade-in.
