    Top speed for the 155hp RXP?

    I know I read it somewhere. What is it?

    i'm told about 60 mph on the dot...

    makes sense to me... the 155HP NA GTX will do 57-58... the 185 HP GTX SC will do about 62... so for a machine with 155HP and less weight and size, i think 60 is a very accurate number to expect. It is proportionate, good at analogies?...

    155 GTX is to the 155 RXP as the 215 RXT is to the 215 RXP ... both sepatated by an honest +/- 2mph

    The 155 has cast pistons and a plastic pump. The 215 has forged pistons and an aluminum pump. Two very expensive changes to make if you're going turbo.
