Great Fit!!!

I ordered this product and it came in faster than I thought it would. The color was a good match for my Kawi. The kit was pretty easy to install myself. Don't forget to buy radiator fluid when you buy this. I had to run and grab some because I forgot. Overall I'm really satisfied with the product and the service.

Hint of Blue

After getting new wheels with Blue Hubs, I wanted to add a little more! So a blue rear shock spring and blue seat cover looked good. But needed a little more, the CV4 blue radiator hoses fit the bill. This round out my bike perfectly, so looking good and functioning great!

Works Great

Put this on my YZ 450 and noticed an instant change. Ride mostly trails in the Utah mountains and could not stop over heating the bike due to the steep and slow moving trails. This pump stopped any and all issues over heating, definitely worth the investment.

DRZ400S

Fit was a little bit tricky, especially the shortest piece but I got it eventually. The bends aren't as precise as stock but they fit and are thicker so you will have to loosen your hose clamps almost all the way to get them over these but they will fit. At least mine did. Bought the green and it looks good. Would buy again.
