I love the fact that I ..." "I bought this mix and match kit for my 1999 Yamaha YZ125 2 stroke. I love the fact that I was able to add a little two tone to my bike. I got the Blue: radiator shrouds, front and rear fender and the Black side panels and number plate. They fit perfect and my baby is looking quite fresh. What was the best part is I didn't think it was possibly to get brand new plastics for a bike that is 14 years old. I've been buying parts, protective gear and riding gear for my boyfriend from Motosport since 2010 and he has always been happy with everything he received from this website. He bought me a bike last Christmas so now its my turn to buy new parts and gear for me!!"

Works Connection Radiator Braces Works Connection Radiator Braces Works Connection Radiator Braces Jarrett Great Quality But Low Protection "I love works connection's products and have always thought their stuff was top notch. I ..." "I love works connection's products and have always thought their stuff was top notch. I purchased a set of these for my 2013 KX450F as insurance to possibly save my radiators in the event of a crash. The fitment was excellent and the quality honestly looked great. My first crash on the bike I cased a double and high sided. Both radiators were destroyed. One brace sandwiched and the other just bent. I would suggest you save your $ and put it aside for an aftermarket set of radiators."

"I wanted over the boot pants and something that wasn't too loud (flashy). I was in the market for a solid black pair and these are it. I think one leg has a logo on it and something small on the other side but that's it. The padding built in on the inner knee is perfect too. These pants were just what I wanted and they fit perfect. Jersey and gloves are top notch as well. Great combo."

"My first time out wearing this I took a spill over the handle bars and came down hard on my left shoulder and rolled a few times. I immediately popped up and wasn't hurting at all. I was very impressed with this product. I put it on every time I go out, even if it's a gentle ride. If you are like me and not as young as you once were then you'll appreciate the extra protection. Fits great and stays put too!"

"Thought these would just be an impulse buy and not really needed...But after using them once I will never ride without them. They fit great, my feet loved them! I wear over the boot riding pants and these socks go just past the top of my boots for a perfect fit. Very glad I splurged on them at the time."
