Welcome to Mountain Motorsports!

“Had my 08 RZR repaired and John in the service center was great. Fixed the problem, was informative and the price was right. I would highly recommend Mountain Motorsports for any type of service you need.”

Hans Nesbitt: “I would encourage all to feel VERY welcome at Mountain Motorsports. I have a long history of dealing with this family owned business. They ALWAYS treat you as if you were in THEIR family. All the way from the front desk, to the techs in the service bay. You will feel reassured about your most minor concerns which will allow you to enhance your Pomona Valley dirt bike experience. My 2008 Suzuki RM-250Z is a new machine after taking it to Mark and John at Mountain Motorsports. They have predictable door hours 7 days a week. As a Vet MX’er they have rejuvenated my dirt bike lifestyle. Thank you Colin and Shawn for a lifetime of high quality support for my Suzuki MX lifestyle. I TRUST this longtime local business!”

“I just wanted to commend Mountain Motorsports for being one of the best shops in California. I called 22 shops trying to find a certain scooter, no one had any. But when I called these guys, they didn’t have one but told me they could get one for me! They could see that my mind was made up on what I wanted and didn’t try to talk me out of it or sell me what they had…they not only found one, they went all the way up to Northern Ca. to get it for me. They were friendly, patient and extremely knowledgeable. I will definitely be doing business with them again!”
By: Marilyn Griffin

“I just wanted to comment on an experience I had with one of your staff. Last week I spoke on the phone with Jason Green. Considering my needs were small and to some extent extraneous, I found him informed, engaged and surprisingly accommodating based on my experiences with other dealers, and very willing to go the extra mile to help me in every way that matters…Typically, young guys who work behind the counter within this industry, seem to have a sense of arrogance and/or an elitist attitude- too cool to help the old dude. As a business owner myself, I am aware that what we do, and how we treat people, is who we are in the eyes of the public, all the way down to the entry level guy- even his behavior sets the tone and the impression customers have of my company. I found your guy to be a breath of fresh air and will continue to source my motorcycle needs as they present themselves from MTN from this point forward…Thanks for the ear and please pass on these words of thanks and gratitude to the appropriate personnel for review. Jerold”

By: Jordan Ralston

“I thought the sales rep did a great job, Jason in accessories is great with recommending the right equipment. It makes riding a lot better with the right equipment.” By: M. Crandall

“What a great experience my son and I had when purchase our bikes in two separate occasions. Will definitely talk to friends and family about Mountain Motorsports and support their business to last longer in my city. Thank you guys and keep up the excellent job!”
By: Rudy Ramirez:

“My technician, Robert Paez, installed my rear tire wonderfully. He adjusted the rear brake without me asking, and it is great.”
By: Bob Eastwood:

“Dave thanks for all the hard work and not giving up. The dedication you guys at Mountain Motorsports deliver is amazing. They know what customer service is all about and will fight to the very end to get you taken care of. Walked out with a new Honda CBR600RR and could not be more happy. Thanks again Dave and team.”
By: Allen Fox

“I’ve been in for parts and things before but this was my first time as a motorcycle buyer with you folks. Every aspect of the purchase was handled flawlessly and yes, I’ve bought bikes in the past so I know how it works. I was able to keep one bike at the store while riding my new VFR home, follow-up was great and Tony even managed to find a seat cowl which I forgot about during the purchase and he did this happily after a few weeks had gone by. Some places don’t even remember you the day after a purchase. Not only do I recommend Mountain Motorsports to friends but I definitely return when I need another bike. These guys know customer service."
By: Greg Nelson

"My purchase experience was a pleasure. Tony Mangiagli did everything within his power to make sure I got the bike I wanted and gave me deal I couldn't refuse. Best price anywhere and treated me like a valuable customer. I almost feel guilty with the deal I got. This dealership makes you feel like part of the family. Thanks Tony. "

They did a great job selling me a quad, the sales guy including the finace department were great. "
By: Anonymous duarte,CA

"I would like to thank the folks at Mountain Motorsports for the great deal on the 2007 Harley Davidson I purchased from them. They offered a great internet deal with a print out of their motorcycle ad. It saved me $1000 off from the price tag on the bike. I highly suggest you take a look at the internet site. Further more they were polite and knowledgeable and answered all my questions. The finance process was fast and simple not to much hassle. I would also like to thank Gabriel Houston the sales associate a true professional at his job keep up the outstanding job. "
By: Mario Oxnard,CA

"I saw your ad on the Polaris rzr forum and saw that you have Polaris rzr accessories in stock It was very cool to have a rzr on the floor with some polaris accessories installed including the hood scoop."
By: Lee Rancho Cucamonga,CA

"I would like congratulate you on your salesman Ken, he was personable,professional,helpful and courteous. So far i am very happy with my used kawasaki 650. He did everything correct and I was very pleased with him. When I am ready for another bike Ken will be the first person that I go to. Please thank Ken for me. Sincerely R Peterson "

"Mountain Motorsports treated me great! The sales guys are really helpful and not the usual type that you usually run into. They spent a lot of time with me. I shopped around and I know I got a solid deal. I love the bike. Thanks for everything."
By: David Rancho Cucamonga,CA

"I honestly have to say that I'm very pleased that I bought my 2008 Hayabusa from Mountain Motorsports. I'm very critical on how I send my money... and who I give it to. I live aproximately 2 miles from a very large dealership, but I couldn't find a single bike owner that didn't feel like they were screwed over(you guys know who I'm talking about). Even when it comes down to basic maitenance... B*rts tried to screw me over. Look, I made a sound investment... because you guys run your operation... like a well oiled machine. I know times are tight right now, but you guys at Mountain Motorsports keep being who you are... and you'll be around for a long time(and you'll keep getting my money). I'm speading the word... believe that!!"
By: Michael west covina,CA

"Overall, I've been very pleased with the scooter and Mtn Motorsports. I had a few rough patches with getting the parts shipped from Lance to your store, but other than that, it's been pretty good. I would definitely recommend you again. I wanted to mention that there is a website called that has been INCREDIBLY helpful in getting going with the scooter. Primarily, the forum is a very large group of other scooter owners that help with all things regarding scootering. Is it possible for you to share this resource with others that purchase scooters from Mountain Motorsports? It would very likely improve your customer service experience (not that it is lacking) in that you offered them a place to get helpful tips and answers to many of their questions, just like I had. Thanks again. Kevin"
By: Kevin Upland,CA

"I am a 40+ y.o. woman and I have purchased 2 Honda motorcycles from Mountain Motorsports in the past 18 months. I was treated with respect, courtesy and genuine interest by all staff members. I did not feel rushed or pressured during my bike purchases, and the service staff always takes the time to answer my many questions. Thank you Mountain Motorsports! You'll always have my business!"
By: Brenda Ontario,CA

"I want to thank Mountain Motorsports for providing me in purchasing my new 2007 Honda TRX 450r and was able to practice and pre-run for the 40th run of the Baja 500 this year. We, SouthSide Racing were able to finish 6th in our class (sportsman atv) and 119th overall. Not bad for for a field of over 300 entries. Here is a few of me and the team pics. And thanks again could not have done it without you guys and expect us back for the 1000. Thanks Alot, Robert Valenzuela 52a p.s. Thanks for your help Anthony "

"today brought my cbr1000rr in for repairs stator went south. So it happens that american honda has issued a warranty for this issue. I called several dealers in the area not to point fingers but they are the two that are the biggest ??????? They didnt care or had not heard of this issue called John at your dealership he knew exactly the problem and was aware of the bulletin from Honda. He was very helpful told me to bring it in and technician David would diagnose the problem as expected it was the stator so David installed the updated parts. I got there around 10:00am was done by 1:00pm in & out I can not express enough thanks to your company. Having John and David is truly an asset to your company. Awesome customer service from point a to b! So please give those 2 guys a pat on the back for me again thanks for the quick service "
By: ERIC alta loma,CA

"Your Sales Department assisted me in purchasing a Honda Motorcycle.The customer service, product knowledge and overall demeanor was excellent. The end result was I purchased a bike that day from this dealership versus the other local places I visited. I am a satisifed customer that will be back for more."
By: William Rancho Cucamonga,CA

"I have not yet had the privilege to purchased a bike from Mountain Motorsports but you can be sure when that time comes, Mountain will be the place that I go. As for the service department they are second to none. John and Jim happen to be the two that help me out the most and I always get great customer service from both of them. There knowledge of motorcycles let me know that my bike is in good hands. The ladies at the cashier stand greet you with a smile, appreciate you business and treat you with respect. I would have to say the best thing about going to Mountain Motorsports would be you are never attacked by there sales team, when they do approach you and you say "I am just looking" they will step back and let you do just that, unlike at Bert's Mega Mall where they treat you like a number and send the "sharks" (sales team) after you until you either buy or leave. From management to the person that just started you are always valued as a customer."
By: James Chino,CA

"i have been a customer with mountain motorsports since 2004. I continue to purchase atv from here, because of the sales staff they have there.
