Corbin sucks.
I had one and sold it immediatly at large loss.
Unless your built like an arangutang (sp?) they suck.
Felt like i was sitting in a bucket, could not move around on it, felt like sitting an a horse saddle., but worse.

actually shaped to push you further away from the bars, and sits lower and closer to the pegs, so stretch to bars and legs cramped, azz stuck in hole since they make it like a cruiser seat.
For guys who are 6 feet or taller with 30 inch inseam

, and don't hang off or, use body english to ride then it might work for you...
my passengers hated it too, as the backrest was so far away from the driver they felt like they were hanging / dangling out back there, and yet the slope caused them to slide forward all the time.
Corbin pretty much refused to modify it for me, and shipping made it prohibitive anyway.
Get a conny gt1400 seat, everyone who has seems to really like that setup.
