Dang, this's a good thread, Jen. Just got on here, after not signing in for a couple of months. Just want to add my $.02.
I'm 76 and have had my 08 RS since 010. It's been love/hate since the day I got it home (a 5-6 mile test ryde won't tell you what you need to know for buying any machine!). Been modifying it ever since, and the love/hate has gradually changed to more love than hate. My home-made foot boards are 3 inches lower, the brake and shift levers are re-located some 18 inches forward, the bars are 4.5 inches higher and the windshield is 27 inches tall, now. But, I'm 6' tall and weight right around 208 with riding clothes on, so, I expect that you'd find an RS much more suited to yourself than I did.
I have always found the clutch and transmission to be as good as any bike I've ever ridden, and the last time I counted, I've ridden some 30+ different makes at some time or other. The reverse is the best in the business, as far as I'm concerned. I've had no complaints with the ride and handling; I love the quick steering. I did have the dynamic/electric steering gear change, under warranty. The brakes have been fine for me. Fuel mileage is a joke, but I live with it. Best tank I've had was 39, worst was just under 25. The engine is rev-happy, but I, being an old fart, have a tendency to keep it below the "happy" range. It likes to be above 4000 much more than below. I've never had it above 7000 rpm, that I can remember. Well, there was the time I hit 97 mph for just about 2 seconds, which felt real good, but had me pretty puckered, looking for "black and whites" and hoping I didn't get a sudden cross-wind, or some critter didn't cross my path.
I do all my own maintenance, so I don't notice those costs any more than to note that parts are spendy, but you know that drill already.
You've been on a "sport bike" I see, so I think you'd like a Spyder for handling. When riding up in the Texas Hill Country, my two-wheel buddies pull ahead in the long sweepers, but I always catch up in the tighter sections, which is/was a surprise, early on. The thing certainly has capabilities far beyond what I've ever dared to approach.
The suggestion to try an F3 sounds like a good one, and I intend to do so, myself, one of these days.
Please forgive the long-windedness. Just had to chime in. You've already received a great response from everyone else on SL's, but thought you might like to hear from someone who has missed his two-wheeler, but has made the "adjustment". BTW, I only made the change to make it easier for me to accommodate my wife of 55 years, and may, yet, get back to two-wheelin. Dreamer!
Good luck, and let us all know how you make out.
