Of the big heavy ST's the FJR is the most nimble IMO. The engine is great, very low upkeep and it is very durable. The shaft drive is stout, coming from a chain driven bike you will feel the shaft lag. Its not bad though, I loved the low maintenance.
On the 07's, look for the completed recalls, the ECU was replaced, the ignition switch, chassis spider ground and probably something else... The 07's had more issues than the other years but the cherry red was my favorite. I highly recommend a G2 throttle tube to smooth out the throttle. Some guys mess with the throttle springs, but the throttle tube helped my 07 enough. Made it much better in first gear hairpins.
