KTM RC125, This sporty 125 has only covered 538 miles from new by one local owner. Just had it's first service and is in superb condition and ready to go. The 124.7cc single-cylinder motor is actually a lot smoother than the RC390’s and despite its modest A1-licence-enforced 15bhp, the 135kg machine is still extremely nippy. It’ll do 73mph on the flat, and with your head down under the short screen, feet on the pillion pegs, downhill with a howling tail wind it’ll crack 78mph, bouncing off its 11,000rpm rev-limiter. Every mile per hour counts on a.
