The S4RS. Man, those things are another category altogether. Effectively the bike we're both used to with considerably more top end power.
I wonder how well they plod along in traffic?
Well... I test drove one S4R that needed a lot of work. Not a cruiser - you have to be an active participant. lol If you enjoy instantly accelerating and stopping, then this is your game I guess. One nice thing about it (for traffic) is that it is water cooled, so it doesn't overheat as easily as the S2R. I was afraid of this bike before riding it, but honestly, it felt a lot like the S2R. Maybe a little more stable and heavy, and a bit more power, but this one needed work, so it might be a true mean machine if it has some TLC. With that said, I have been warned that the back tire will break loose for any reason, and this is what happened to the owner who dumped it - he had no idea what happened.
"No, it's not broken - that's just what I tiger purrs like."
