Testimonials

On 12/1/2025 John Morrell had this to say:
2011 Road King. Bought 5 years ago with 30k miles, has 60k now. Moved into area last year. Looked for independent shop, found Thunder Road. Had the bike in for various reasons over the year, most recently cause she just wasn’t running right. They have always done good work, but this time they out did themselves. Tracked down a few issues and have the bike running better than ever has since I bought it. She just purrs. Missy, Tim and the crew are just awesome!
