"I ride a crf 250, I am currently on my 3rd set of valves and 2nd head. 2 of the 3 sets of valves were kibblewhite with KB springs. After breaking these in they don't move and are extremely tough. I ride my rev limiter a lot when I am racing, and these take the abuse without missing a lick. I cannot say enough good about these valves. Unless you are a pro you will get plenty of use out of these before your next valve job."

WHAT CUSTOMERS SAY ABOUT MOTOSPORT

I've dealt with the sales and customer service dept and both were very efficient and professional. Thanks! I will be using MotoSport for the majority of my off road purchases.

- Valued MotoSport Customer

It's a BIG PLUS that the people taking orders ride and are knowledgeable about bikes. I do wish you listed parts for older bikes (e.g., 98 Yamaha's), but overall, selection is good.

- Valued MotoSport Customer

Very Good Selection and Price! Awesome website and will definately buy from again!! Really like the sale prices!!

- Valued MotoSport Customer

I've always had great experiences with MSO and will continue to do business with you folks. Thanks.

- Valued MotoSport Customer

Love your website, this is the first time ordering from, and was very simple and fast. Also your customer service is excellent, have ordered from in past via phone and your guys are super nice and very smart and friendly. A++++++!!!!

- Valued MotoSport Customer

Since I started ordering from you guys last year I have always gotten my orders on time and you have always been very helpful.

- Valued MotoSport Customer

Your web site is by far the easiest I've found to order from. Being able to list all of my bikes, select one of them and then order parts from your lists is super easy. And your pricing is usually a little cheaper than other sites. Thanks

- Valued MotoSport Customer

I live in Hawaii and the line I hear the most from the ATV parts store is "I don't have it in stock but, I can order it". I decided to go to the source... MotoSport.com. I figure, why wait a week or more, you guys always deliver in a VERY reasonable time.

- Valued MotoSport Customer

I have ordered many things from you guys and I have always gotten it quick. I really appreciate everything. You guys are awesome!! Ride on Ryan

- Valued MotoSport Customer

Very Happy, needed to replace the head and cams on my 05 kx250f and there was a pro circuit complete head for a sweet deal. Couldnt pass it up.

- Valued MotoSport Customer

I would like to say you guys have great customer service along with having my package get to me away early was the kicker to me being a customer for life. Thank you

I would say that I am one happy customer and you guys must be doing something right. I shop your store for ATV tires via the internet but if I had any problems or questions I just dialed up and your sales people were great.

- Leni from Catawissa PA

You guys are leading the world in e-business motorcycle goods. There are a lot of other online sites that could learn a bunch from how you guys operate. Thanks for the prompt, pleasant and quality service.

- Valued MotoSport Customer

I was really impressed that the tires I ordered were delivered exactly when you said they would be! Good Job!

- Valued MotoSport Customer

You guys do a really great job. You have great product reviews, and I love the idea that you can ask a question on a product and you will get an anwser with in a few days. Keep up the good work, I will always purchase my motocross stuff from motosport.

- Valued MotoSport Customer

I think Motosport overall is awesome!!!!!! Every thing that is on my bike is all from Motosport, and it's fast and easy to get. So I thank Motosport from everything and I'll be back again. !!!!!!!THANKS!!!!!!!

- Valued MotoSport Customer

I discovered Motosport Outlet about 2 yrs ago and have been hooked. You guys do a great job. Keep it up.

- Valued MotoSport Customer

I buy from you because of your 2 day shipping. Your prices are very comparable to others. Most things cheaper. Your site is easy and quick and I like how it remembers what my ATV is every time that I go to your site.

- Valued MotoSport Customer

You guys have a great ATV tire selection. Motosport.com is definitely easy to use, and is helpful with any questions you may have. Keep up the good work!

- Valued MotoSport Customer

I always check out with ease and it's very convenient how I can put stuff in my cart - prices during sales and everything - and they still be there a month later.

- Valued MotoSport Customer

I really like shopping on MotoSport! Its always easy and even if I spend a lot of money, I always seem to save a lot, too!! And I love that I always know when everything is going out for delivery so I can plan for my things.. One happy girl!! :]

- Valued MotoSport Customer

Just wanted to let you know that you're doing things right! Your website is very easy to navigate, the schematics are outstanding and the reviews are helpful. Furthermore, your customer services reps are friendly and helpful!
