Well ferret you are dam close it is a 1975 cb400/4 and those are oem bars these are Canadian model's, the cxt's have low bars to. The Yamaha dirt bike is wr250r, and the black cover is covering 03 fjr 1300,and the silver cover is covering a cx650t.
Inline 4 the inline 4 make's a sweet sound, but for the sweetest sound is one of my cbx's with six into two pipes.
I do love all motorcycle's but some just steal your heart and ears.
But I am getting off track here, I really like the power box two tails pipes with the stock header, but can not wait to hear it with the arrow header with no cat. The snow can not go fast enough. That is the nice thing about winter in Canada you can not wait till spring and all your bike's feel like brand new.
