ya this is true. they are basically the 4stroke replacement to the old Blaster. its taking the place of the Blaster in the ‘sport’ lineup. if youve ever ridden a blaster, i garauntee you you will be cramped on it , as an adult, and its not the fastest quad out there by any means. its a somewhat low-tech 4stroke engine, but for what it is intended to do, its a good quad.
