Honda NSR150

The Honda NSR150 is a motorcycle produced in Thailand by Honda as the Honda NSR and in Taiwan by Kymco under the name Kymco NSR. The early Taiwanese NSR150s were built with engines imported from Japan, but later models used engines cast in Taiwan by Kymco. Because of local regulations the Kymco NSR150 had less power than the Thai-built ones, since its carburettor was smaller and the ports in the cylinder slightly different in size, and it is common to switch to a Thai-made cylinder for NSR racing in Taiwan. Because of a large number of warranty claims, the CDI was programmed to open and then close the RC valve, since running cheap two-stroke oil reduced engine power further. The Taiwanese and Southeast Asian NSR150s are closely related, sharing the same stroke and appearance.
