Rockster handling vs. roadster handling?

I know the differences in spec and parts. What kind of difference in handling do all the changes result in? (Granted, I know it's pretty hard to separate the differences in "feel" caused by suspension/rake/trail/ numbers and those caused by the ergos, but hey).

ime... Rockster is a little quicker to turn in, the steering is quicker due to the "lifted" rear but I'm not sure if there's any difference in the actual ride-height setups of the front of the bikes (the Rockster has the R1100S front end, the Roadster is (IIRC - could be wrong) the same as the R1150RS/RT).

apart from that, there's not a lot in it, I don't think.

I tend to agree with riceburner: there's not much difference in handling, at least when compared to a broader selection of motorcycles.

When we had both bikes (wife's hand-me-down Roadster and my Rockster), the handling difference was easy to discern. Based on combination of handlebar bend, ergonomics (body position effect on both center of gravity and weight/leverage on grips), and suspension setup, the Rockster was definitely the "quicker handling" bike.

But when either R1150R variant is compared with a range of moto-options spanning sportsbikes to cruisers, I'd say the Roadster/Rockster feels like a nice unibody SUV (BMW X3, Ford Edge, or equivalent). Using such analogy, my Buell handles like a Shelby Cobra (twitchy & inelegant, yet invigorating), most 600/1000cc crotch rockets perform like true sportscars ( Porsche Boxster, BMW M3 being good well-balanced examples), and Bad Boy cruisers are like ladder-frame pickup trucks that despite big torque/tires/V-motor exhaust decibel barrage just cannot and will not handle well.

Isn't the front shock of the Rock slightly shorter than the Roadster (and the rear shock slightly longer)? I vaguely remember reading this on the forums. So I assume the Rock has a slightly steeper rake and less trail. Maybe not enough to make a significant handling difference between the two, just something to note for the obsessive ;)

Not sure about the fronts (I'm still on my original front shock!!!), but the rears are quite definitely different. I have a R-R shock on my Rockster at the moment and it drags its arse like a sheepdog with terminal piles. :(

I think the difference in length is about 1/4"-1/2" - not sure exactly although I think I do have a photo somewhere of the two shocks side-by-side.

Whoah, it makes that big a difference? Gonna be problematic for Rockster owners then. I'll bet Roadster shocks will be cheaper and/or easier to find.

Any of the shock companies can build a Rockster spec'd shock. I had Ohlins built by the speed shop and the cost was comparable to ebay prices.
