If your vintage Honda motorcycle is running rough or won't start, the ignition condenser might be shot. This RW condenser is made in Japan to original specs, and it fits 1978-1979 Honda CM185T Twinstar, CD185T, CD125T, and CM125T models. It's a small part that works with the points in the ignition system. Easy to replace if you're doing a tune-up. Always double-check your bike's year and model, but for these old Honda twins, it's the right part to get you back on the road.
