BETAXTRAINER 300 2017 - Present

　　The amazing 300 Xtrainer returns as well for 2017 with an updated graphics package. The motor is based on Beta’s 300 RR, but has been detuned. It has milder cylinder porting and there are spacers in the air intake tract and the power valve air chamber to mellow everything out. Another difference that’s easy to spot is the bike’s expansion chamber, which is overall smaller and has a more squared-off shape, which gives the motor more bottom end and less of a hit.
