I don't own one but I ride with two guys that own the rxpx 260,
First, totally bad azz ski's, IMO the perfect combination of style, performance, handling, I really don't think there is a better model out there, although there are some close 2nd's....
Second, the ONLY downside I can find is with the fuel consumption, the best word to describe it is "terrible"
I always have to make ride plans around these two clowns because they are always running out of fuel. Granted they are both in their mid 20's, love speed, and rarely lay off the boost, which is the problem. now some of my buddies that have the same power plant but are in their 40's (ie: they behave) seem to get significantly better fuel economy.
they only way to get acceptable (not good, just acceptable) fuel economy is to avoid pulling a Cole Tricket. "I'm dropping the Hammer Harry !" and based on our little expierements it has a lot to do with how quickly they go from 0-50, which is our normal cruising speed, if they hammer it up to cruising speed, or do a lot of horsing around, such as 180's, or hard s-turns, general jackazzery, then i'm
lucky if they can run 60-65, tops 70 miles before I hear their buzzers going off. So in general they are running somewhere between 4.6 mpg up to maybe 5.2.
When I ride with my older buddies, we are easily pushing 10 additional miles without any trouble at all, approx 5.2 up to low 6's. The key seems to not hammering from a dead stop and keeping cruising rpms under 5K, econo/touring mode.
The only downside to behaving, is it isn't as much fun thinking about conserving fuel as it is being Cole.
I haven't had to tow either of them back to the dock yet, but its just a matter of time
my only advice is to behave through half the ride, and 1/3 of the way back, then start with the jackazzery, and you'll make it back on fumes, but with a big smile on your face.
