“I trust my softail to Mark at Twin Thunder the best Harley Repair shop in Lost Angeles.”Daniel Rosen, Culver City
“Mark does amazing work, always at an awesome price. I’m so glad I found Twin Thunder.”Phil Stellar, Venice Beach
“This amazing harley shop is a hidden gem”Fred Rosen, Beverly Hills
“What a gem of a motorcycle shop. The owner Mark is intelligent, interesting, knowledgeable, helpful and has a great attitude. A true motorcycle enthusiast that enjoys what he does. I would highly recommend his services ”Greg M., West Los Angeles
“I’ve been to a handful of shops in LA, but Mark is the best I’ve ever been to- The pricing, the passion and attention to detail, the attitude, everything! He has worked on my bike and always been fair and honest. My bike runs and shifts now like it came off the show room floor. Come here if you want your bike worked on the right way, the first time.”Nadar Y., Los Angeles
“Mark is a super cool guy- straight shooter and always helpful. Mark ordered parts for me several times while I was rebuilding my FXR chopper, and even though he was not doing the wrenching he totally helped me out and even double checked to make sure I had the correct part for my specific year of bike. Most shops won’t give you the time of day to order parts for you if they are not doing the work, let alone help make sure what you ordered is correct. The prices on parts through Mark are the best I’ve found in town, he’s a Drag Specialties authorized dealer so be sure to check him out if you need something.”K.L., Beverly Hills, CA
“I’ve had my custom chopper at 5 different shops for numerous repairs, and Mark at Twin Thunder is hands down the best shop of them all. Honesty, attention to detail, experience, knowledge, this guy has it all. He called me every few days with a status update which was great. Add fair pricing to the mix and this place is a no-brainer if your bike needs work. Highly recommended!”Oliver D., Beverly Hills, CA
“Mark is a master at what he does you can tell he truly lives to see his work enjoyed old school builder in a modern world. I found him more then helpful don’t know what nick p is talking about this is not McHarley repair shop expect to have a skilled Master work on your Sled. And honest is really understatement.”Jay B., Los Angeles, CA
“Mark is a great asset! Needed a starter for my EVO and was shot down everywhere I called  (even the dealer) but Mark was eager to help me out and searched his stash for me. I drove up to his shop in LA from San Clemente. We spent about an hour making sure I was getting just what I needed; I even learned some new stuff! Great to have Twin Thunder in my arsenal!”Mike N., Capistrano Beach, CA
“After dealing with my Harley dealership for 6 years, I finally woke up. Mark is faster, more honest, and way more friendly than the guys at the dealership. I don’t know how it would’ve been if I were a male rider or had a nicer Harley, but the dealership repair experience was always painful. As long as you don’t mind girly magazines laying around (I don’t care), Mark is your guy. He prefers to work on customizations and stuff, but he helps me out with routine maintenance too.”Stelle S., Los Angeles, CA
