Further proof that gearheads will seek performance improvements from anything, LeoVince has introduced new exhaust systems for the new 125cc Honda Grom. The LV One and GP Corsa Racing slip-on systems allow better breathing and lower weight, producing more power and torque and improving the on-track power-to-weight ratio of the bike. And LeoVince says that full systems for the bike are on the way. Suggested retail for the slip-on exhausts starts at $199, from dealers. For more information, contact LeoVince USA, Dept. RW, 1445 B.
