If you have ever ridden a sport bike, or watched motorcycle racing, you know how much a rider needs to slide from left, to center, to right on the seat to navigate the turns. Doesn't seem like a big deal, but the transitions actually destabilize the motorcycle due to the rider having to lift his/her body off of the seat to shift positions. Not to mention, the constant up/down and side-to-side movements on a traditional motorcycle seat are tiresome on the rider.
Brit-Brothers, a British company (duh), has developed a seat to address the issues mentioned above. The seat has tapered rollers that use friction controllers so you don't just slide off of the seat. The product is still in development but the pictures sure as hell look cool.
