this is a great seat for rider and the occasional passenger.but 2 large humans will find it tight.i have been living with this seat for 9 yrs now and find it very good solo,but when you add a passenger they will need to be on the small side.ive had people on the large side and they intrude on the riders space considerably,add that this seat does push the rider back a bit.also I have noticed that this seat splays your legs apart when standing over the bike eating legroom , mines an 05 standard,i have noticed friends who couldn't flat foot a stop with both feet,who could otherwise with a stock seat.on another note mine was not waterproof from the factory,this is my 2nd rumble seat, the first one was fine ,but was replaced by my ins co after an accident.this 2nd seat made my ass wet every time it rained.i coat it with water repellant every f ew years.you can also jettison that crap mounting bracket and use a stock seat pin, with the key.otherwise youll have to ride with the appropr,iate allen wrench in your pocket in case of any battery or fuse trouble,it seems like a bad design.and did I mention its heavy,my heated version easily weighs double what my stock seat and pillion pad did.another plus for the stock seat pin conversion is it can be easily swapped out for the stocker in seconds.
