Founded in 1991, CPI is a Taiwanese motorcycle manufacturer. They produce ATVs, scooters, street bikes, and enduro. The most famous CPI models are the Popcorn, Aragon, and the SM. The company has been certified in ISO 9001:2000 for creating ATVs and motorcycles. So, before you go tinkering with your CPI, make sure you got an CPI service manual.
CPI manufactured a new generation of engines, with the EURO 2 standard in mind, which reduced almost 70% the emission of NOX and up to 85% the discharge of CO. CPI has factories and offices in Taiwan, Indonesia, China, Vietnam, Europe, and the USA. In 1999, CPI Europe, headquartered in Austria, became operational. In order to be successful, a team of European engineers always has an eye on the quality control in the Asian factories. The EIMCA Milan 2001 and the INTERMOT 2002 were two of the most important places where the Taiwanese motorcycle manufacturer proved to have taken seriously into consideration the idea of quality.
All the Taiwanese motorcycle makers, including CPI, have been able to make significant inroads in overseas markets, notably the highly demanding European and Japanese markets, thanks to the high performance and low pollution levels of their motorcycles, ATV's, or scooters. In 1999, the technological capability allowed the Taiwanese motorcycle makers to meet the second-stage pollutant emission standards set by the Environmental Protection Administration.
Now, the standards set in 2004 required the replacement of two-stroke engines with four-stroke engines. Talking about the famous CPI models, Aragon, GTR and Formula R share a 49cc, 1 single-cylinder, two-stroke engine. The ATV line includes the XS 250 model, featuring a 250cc engine which can develop a power of 1.3Kw at 7500rpm. Its little brother, the XT50R has a 49cc engine with a power of 2,2 kW at 6000rpm. Moreover, when it comes to repairing them, having an CPI workshop manual to guide you can be a lifesaver.
