Yoshimura rs4 slip on exhaust CRF300 

Introducing the RS-4 for 2021 Honda CRF300L and Rally dual-sport motorcycles.

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 Slip-on for the all-new Honda CRF300L and Rally edition, the results were fantastic! Our slip-on provides 14.2% more max power on the bottom end of the spectrum paired with equal top end power as the stock unit.

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

This sock has a seem between 2 toes -very uncomfortable.
These are exactly the socks I needed to wear after breaking my foot, but there is a big, thick seam sewn in, between my big toe and the next toe. Extremely uncomfortable. I had to use a seam ripper to remove the threads on these socks, so I could wear them. We were leaving on a 4-week trip the next morning, I had no time to return them.

That they are not as they appear in photos.
The photos do not show that there is a section for the big toe and the rest is open. The photo shows as if the whole toe section is one opening instead of two. They work for what I want but just not what I thought they would be.

Not as pictured
The pictures make it seem like these are open all the way across. There are actually two holes. It is quite tight on the big toe. I will keep these, however I would not order these again.

Comfortable toeless socks
Very soft and comfortable. However, the elastic is too tight. Should be wider so circulation is not cut and you are able to wear it at night. Therefore, is not good for diabetic and heavier people. Larger sizes should be available.
