Danny Grey Air hawk Big Seat with gel installed under the Air hawk. When I got my seat I was 6.3 and 375 lbs and couldnt find a seat that I could spend more than a few hours on. Once I figured out how to dial this seat in (pump built into side and I kept over filling it think like I do with most things that "more is better") I could go all day. I have almost 30,000 miles on the seat now and it is still absolutely the greatest seat I have ever used on a mc. I no longer weigh 375 lbs but still will never use a different seat.
