Super Cool Radiator

It was delivered quickly, which was the most important part because no other radiator would have arrived in time for my important ride. It went on the bike easy enough, except that the bottom hose fitting was a little off and my Bullet Proof radiator guards did not fit at all for some reason. I'm still gonna work on that. The stock KTM louvers did fit. I like the looks (the flat shiny top) and it has held up so far; two days of desert riding.

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.

Water pump kit

The kit is of good quality. Thought it included the impeller, so check it well before you purchase, as they do wear down in time.

Perfect

Once again Motorcycle Superstore pulled through north of the border. They had my parts to me in less than a week. My old hose melted and I put on these sharp looking and better made hoses by factory effex. Awesome product. Easy to install and looks great. You can tell it is just better quality than stock.

Factory Effex Y Engine Hose Kit

I trail ride a 2009 Honda CRF450R in the mountains of Colorado. Prior to installing the FX hose kit, slow technical trail riding would result in over-heating into my make shift radiator over flow reservoir. I tried Engine Ice Antifreeze and a 1.6 radiator cap but would still over heat when riding slow. With the new hoses installed, I've replaced the 1.6 cap back to the stock 1.1 radiator cap. No over heating after two outings. I am very pleased with the functionality, as well as appearance.
