You may not expect to increase the top speed with this ride plate, moreover you may expect your boat will remain the top speed at the OEM spec, in other words around 65.5 -66,5mph (which is the top speed of a stock Ultra), or even to reduce it just a little bit. However the handling characteristics would improve drastically. Overall this particular SE plate is well matched to the Ultra 250X needs when the rider competes in wavy conditions. SE products are available from Sato Engineering as well as from Jetwave of Fennec group.
