The new 2012 Sea-Doo GTX S 155 carries on in the tradition of luxury watercraft while adding a clever twist, adjustable suspension. In our opinion the ability to adjust your suspension is a huge plus since each rider has a different weight and this impacts the ride. By simply lifting up the seat and with the use of a ratchet, you can set the suspension. With the deck being independent from the hull, the suspension system ca travel up and down 5.5". But as usual, this is not the only clever feature on a Sea-Doo watercraft.
