One of the fastest growing segments of the motorcycle market is the Dual Sport segment and we love the smaller bore dual sport bikes as they are an entry level to get more riders into the sport.

We stepped up to the plate and developed our RS-4 Full System for the all-new Honda CRF300L and Rally edition, the results were fantastic! The full system gives the new CRF 5.9% max HP while improving the power across the entire spectrum enabling the 286cc engine to optimize performance while saving significant weight.

The sound of the RS-4 is unmistakable, on idle and under load the exhaust note is music to ones ears. Also available is our USFS approved spark arrestor for those riders wishing to take to the trails in the great outdoors. Part # SA-13-K-1

Proudly made in the USA!

    The Best Best Best System out there

    Was lucky to buy this system here in Germany through a reseller. The Exhaust system engineering quality is top notch, the packaging and installation manual are great. Thanks to Yoshimura for developing this amazing exhaust system which sounds brilliant on my CRF 300L Rally. The sound is really really something of another level, I cant stop admiring it every minute.

    Yes yes and Yes

    After contemplating for months, I finally pulled the trigger and bought the Yoshimura exhaust for my crf300L….all i can say is Wow
    This thing put a smile on my face the moment I started it up and the install could not have been easier (so many videos on YouTube)…it changed the look of my stock bike and I can even feel some performance gains as well. All in all extremely happy with my
    Product and the shipping time across the border to Canada

    Best System for the CRF300L!

    This exhaust sounds and looks great!

    Under load the bike sounds deep and much more like a real dirt bike.

    The fit and finish are great. I have absolutely no regrets or anything bad to say about this system!
