What others say about us
Honestly, Only modified motors I’ve actually liked and thought were noticeably faster..
I have been working with Tom for about 6 years now. And I say with total confidence that his bike building skills are what helped, and continue to allow, me ride at a high level. TZR builds very fast yet reliable engines, and his knowledge of the inner working of suspension makes for a bike that is easy to go fast on. TZR is truly a diamond in the rough…for now any ways.
I have used TZR a few times and have come away completed satisfied each time. They take the time to explain to you what work they are doing and never push work that isn’t 100% necessary. When working with TZR, you guarantee yourself that you are getting the right work done and done correctly. Top notch in my book.
I say a photo is worth a 1000 words and I have millions of photos of fast riders riding TZR mods.
Just wanted to say that I am very happy with the work you did (total rebuild)! My 2003 Rm 250 is ripping! Starts well, runs excellent! You have earned my future business!!!! Hopefully, it’s few and far between (bad for you, good for me) but nonetheless, when I need motor work, I know who I am calling. Pleasure to talk to you various times throughout the build. I’ve already thrown your name around to my riding buddies. Keep up the good work and the great customer service. My only issue with the rebuild is: I have trouble hanging on to the bike–I need to hit the gym! Thanks again.
Tom bent over backwards to get my bike up and running like it should and worked around the clock! I can’t thank him enough! I was amazed at the amount of knowledge about bikes that this man possesses. We will forever be a customer and no one else will work on our bikes! Thanks again Tom for everything!
