I recently purchased the 400 and 500 atvs. The dealer showed me a rival kit for the 500 for 350 dollars. The instructions were poor but the parts fit. I finally found a spop kit for the 400 and the owner told me it would fit.  Well they sent a package meant for Europe so there were problems. Customer service has been aweful. After two months I'm still waiting for a shipment of a small front end piece to arrive. You know for 450 usd I would expect a more. Fyi no issues using Rival.

The only issues I had with SPOP when I brought a skid plate for my CF800 was the manual wasn't in English I Emailed them and within hours they sent me the correct manual , skid plated fitted perfectly
