I have something to ask to the lady doctor about my old racing bike
Got a quick tour last week of the new PSI shop. Lots of new tehcnology and forward progress under way. I was just there to grab lunch with an old friend and we were both on tight schedules, but I can tell you it was great too see expansion rather than the typical dampening the MC industry has been in. Was shocking.
Thanks man. We put our heads down when when things got tough and it’s paying off. The new equipment you saw is coming on line as we speak. Will allow us to do far more complex shocks in-house. Good stuff for all. In fact, we had to hire more people. We’re not a huge company, but we love this industry and we’re doing our part.
I loved your comment Progressive Suspension. That’s the proper business thinking that makes good companies better and stronger. We keep believing in our business’ and plowing funds back in. It’ll all pay dividends down the road. Well done.
Need basic rear shocks for my 1970 Moto Guzzi Ambassador.
