    I really like finding owner/operators like Konstantin. Sounds cliche but when you own a business…read moreand interact directly with the customer and provide them a service, you're much more likely to care about what you're doing. I needed a front fork seal rebuild on my bike. I'd gone by a big local place up in Kearny Mesa (won't name) and dude was dismissive, like 'ah yeah a couple hours to pull the forks, a couple hours to rebuild...but we're a month out to get you in'. Acted like he didn't want my business and wouldn't even provide a number 'uh yeah like $130/hour times 4 hours, and yeah parts too'. Gel haired, flat brimmed, frosted tip 50 year old goofball. SD moto did a 24 hour turnaround. Yep, actually less than 24 hours. They preemptively got the parts (he paid for them) dropped bike off Friday, picked up Saturday. Beyond happy. I have a valve clearance coming up in a few thousand miles and I'll coming here. Also he's from Bulgaria , not Russia. Good guy! Edit Bulgaria NOT Belarus haha. Sorry!

    I was having my 2006 Kawasaki Zx10R serviced by a cycle shop closer to my area for years called…read more(motozone) on el cajon blvd but one day the main mechanic there named Roger told me my bike was too old for them to work on so I then stopped going there & I woiuld not recommend them to anyone. I then came across SD moto repair & found brother constantine. He is a 1 man worker but he does work at a fair price, & does it a good time frame & i have been taking my ZX10R to him for some years now for oil changes, tire changes, brake & master cylinder work, front & rear sprocket & chain replacement etcc.. he was even able to find me a replacement fairing for my Zx10R which are hard to find now because of my bikes age & he helped me today (9/13/25) properly fit a green rear seat cowl on my ZX10R that I bought on Ebay that is seen in this photo. I would reccomend him to any rider that needs their cycle serviced for fair pricing, good work & good turn around time. He also doesn't tell his customers "your cycle is too old" as the motozone mechanic told me years ago.
