For 15 years i thought that in order to get good mechanical service i had to take my bike to the dealer. I'm ashamed to say I've been wrong all this time. With another visit to the dealership where i left with the feeling not that of a valued customer who's spent over 25k in 10 years but that of merely a number and one might say a burden. I then decided to take a chance on a referral from a fellow biker. Boy where has Fastline Performance been all my life! Not only was the service quick, no nonsense and to the point, so was the mechanic who also happens to be the owner. Jeff Stern immediately validated the referral given to me by my friend with immediate service, valuable instructions, expert knowledge and most importantly a sense of caring not only for my bike but my safety as well. The dealership shackles have been cast off! Fastline Performance will now and forever be the only place i have my bike worked on. read more

If you don't take your motorcycle here, you're making a mistake. Jeff is an absolute genius. I nailed my bike in some gravel in town on the last leg of a 3000 mile road trip and almost got stranded in Vegas since my KTM OEM brake assembly is back ordered until December! I had almost given up hope and was arranging a tow back for 500 miles when Jeff took 20 minutes to compile a new brake assembly from other bikes and got me going in an hour! Literally saved my trip and I'm still riding on his creation, frankly works just as good if not better than the OEM! He saved my trip, saved my bike, and saved the next four months of riding for me on my brand new KTM Duke 790. I actually can't thank him enough. Take. Your bike. Here. read more

So glad Jeff decided to start a shop of his own! He has built race motors for me and done suspension on every race bike I've been on for over 12 years. His knowledge, experience and straightforward approach to business is unmatched. I'm in CA and I don't hesitate to send him things I trust my life to as a racer. He's done yet another amazing job with my most recent race forks making an OE set of Showa forks into something that works like a $5k set of Ohlins! He's done it all and can do it all, look him up, you will be amazed at the results and service! read more

Jeff Stern is one of the best in the business. He has been building bikes longer than most of the riders have been riding. He has been building / maintaining my CBR1000rr track bike since it was new (2011). Never a failure or problem. And i BEAT on that poor thing. We have several trophies to prove his work. The tune is always solid and the bike behaves like its on rails. If you need simple bolt ons or a spec. built AMA class bike he is your guy. Tuning, suspension he does it all. Could not be more pleased. read more

Jeff fixed a major fault on The KTM 300XC-W WP shock. The factory setting sets the rear ride height to high in the rear, making the bike unstable on fire roads as well as single tracks. Jeff milled an internal spacer which lowered rear about 3/4". Re-valved and used Motul fluid. Jeff then installed a diaphragm filler nut on reservoir, set to 150 PSI. Bike is now more stable with more traction on rear and easy to plink on the slow stuff. With less weight on front the whole system is in balance. Nice Job. read more

Jeff made things very easy for me during my purchase. I'm a bit of a picky guy when it comes to my stuff and Jeff sent me pictures and everything I wanted since, I am not local and couldn't see it for my self. He was also very patient when it came to finaly making the deal cause it took some time to get my local friend to visit him and close the deal. real funny guy too and very knowledgable when it comes to bikes. Would highly recomend him to any one living in the Las Vegas area! read more

Highly recommended. Jeff fixed my 1990 ZX11 where other shops couldn't (including 2 Kawasaki delaerships!!). He is now my only stop when it comes to repairing or servicing my bike. I just got my ZX14 back from him and not only was the valve adjustment hundreds less than the dealership, he also gives you a print out of what he did and how your bike is running. Can't say enough. If you own an old or new bike, Fastline is the place to go. Well worth the drive!!!! read more

I needed to have the gas tanks on my Harley resealed as the liner was flaking off and plugging my fuel system. We walked into Fastline and although this is not what they typically do and Harleys are not what they typically work on Jeff was more than willing to take on the task and help me out. I couldn't be happier with the way I was treated and the personal service provided by the owner operator Jeff. I would highly recommend this business. read more

Jeff did an amazing job on my sports bike. After my motorcycle accident, Jeff took care of everything and even took the time to educate me on what needed to be done. After he was completed with the work, the bike was returned to me in better condition, compared to when I purchased the bike used from the dealership. Very knowledgeable, and once you get to know him well enough - he's very personable and takes much pride into his work. read more

Last weekend, there was a race at LVMS and I had burnt out my clutch on the first start of the day. I asked around the pits for a clutch as well as called the local dealerships. No one had one. My crew chief informed me that Jeff usually has everything a racer needs for a repair job. He called Fastline Performance and he was right!! Jeff at Fastline saved the weekend!! I will be eternally grateful for Jeff and all his help. read more

After I swapped a new exhaust and installed a power commander on my R1 the next step was a Dyno and tune. Having never met me before he not only got me in the same day I walked off the street but he had my R1 running smoother while delivering more power than I could imagine. Jeff knows his stuff and clearly has a passion for what he's doing making you feel confident your bike is getting the best. read more

I needed a new valve stem and Jeff the owner was totally professional and courteous. He didnt make me wait. I rode around back, he took the bike right in and was done in about 20 minutes. Also he answered alot of my questions patiently as I know he was busy. But he kept a smile and I plan on using him if I have anything else I want done. Good guy and he knows his stuff.. read more

Jeff is seriously a no bullshit kind of guy, had me in and out in the same day, and was brutally honest about the parts I was trying to use and thoroughly explained every last question i had about them and my bike. 10/10 recommend. This guy knows his shit and won't jerk you around. Thank you very much Jeff! I will be coming back! read more

I have known and trusted Jeff from Fastline for 11 years. He might seem grouchy some days, but it's for your own good! He is one of the few tech's around that knows just about everything about your motorcycle....and if he doesn't he has the resources to get the right answers. Jeff has never steered me wrong. Highly recommended!!! read more

My experience with Jeff was great! His knowledge and expertise are second to none. Really easy to work with and got my bike working great again even after my visit to 2 other shops didn't bare results. And he's very straight up with you about what you need and what you don't. I highly recommend going here! read more

Jeff dialed my zx-10r in! Installed new chain, performed dyno and fixed bastardized prior owner snafus. He went above and beyond with clear communication of what goals I could achieve and billed what he quoted. He knows what he's doing Jeff is very conscientious and is a brilliant mechanic. read more
