I was in the market for my Yamaha 125Z DX bike's rear indicator cover, I couldn't source it out on many big auto parts shops, I came to know that only Yamaha Dealer has all the parts of Yamaha bikes and other shops have only Honda bikes parts etc. So I bought one indicator's plastic cover in 100 Rs from the Yamaha dealer. My query is why Yamaha bikes parts are not easily available in auto markets on open rates like Honda bikes?
