While Honda, Yamaha, Suzuki, and Kawasaki are the most well-known and prominent Japanese motorcycle brands, there are a few other smaller Japanese motorcycle manufacturers as well. Here are a couple of additional Japanese motorcycle brands:
KTM (Kajiwara Motor Trades): KTM is a Japanese motorcycle brand that specializes in lightweight, off-road motorcycles. They produce a range of motorcycles for various off-road disciplines, including motocross, enduro, and adventure riding.
KYMCO (Kwang Yang Motor Co.): KYMCO is a Taiwanese motorcycle manufacturer that also has a presence in Japan. They produce motorcycles, scooters, and ATVs with a focus on practicality, efficiency, and affordability.
It's worth noting that while KTM and KYMCO have a presence in Japan, they are not exclusively Japanese brands. KTM originated in Austria, and KYMCO is based in Taiwan.
These are smaller Japanese motorcycle brands compared to Honda, Yamaha, Suzuki, and Kawasaki, but they contribute to the diverse range of motorcycles available in the market.
