I did.
The effort it takes to switch direction is similar, sometimes even a little lighter on the FJR due to its wider bars
Steering is very neutral, however, I feel you do have to pick your line before you turn, as the weight of the bike makes it harder to change your line than it takes on the VFR.
Ground clearance sucks.
Stability at high speeds (>90mph) isn't 100%, but I largely deposit that onto the rear tire which has worn nasty flat by the previous owner. I ordered a fork brace though nonetheless.
After being used to fully adjustable, high quality aftermarket suspension, it takes a little getting used to a standard setup. That said, with 30k miles on the dial, the stock suspension is not exactly fresh anymore. Saving up for new suspension again.
Comfort is wonderful. My VFR is tricked so much to the sporty side, it puts strain on arms and shoulders for an entire day. After 8 hours in the saddle of the FJR, I am not even tired.
Luggage capacity is total bliss.
The torque and power are addictive. The way it just pulls when you twist the throttle, at any speed, any gear and any rpm is just amazing. I've gone up an 8% incline at 50kph in 5th gear at 1800rpm and it just accelerates up without so much as a twitch.
In all, great handling bike for long distance sports touring and with better suspension and slightly raised rear for more clearance, I imagine it will be close to perfect.
