Hello everyone and welcome once again to Motos and Friends—the weekly Podcast brought to you by the editorial team at Ultimate Motorcycling.
My name is Arthur Coldwells.
In this week’s first segment, Senior Editor Nic de Sena rides the much anticipated Yamaha MT-10 SP. That’s the model with the Ohlins semi-active suspension. It’s only been available in Europe for the last couple of years, but finally the good news is, that it’s coming to America. The big question is, whether the extra 3k you’re going to have to pony up for the Ohlins is actually worth it, or perhaps there’s just not that much improvement over the stock KYB suspension that has suited the Yamaha MT-10 so well until now?
In the second segment, Associate Editor Teejay Adams chats with Val Collins. Val grew up on motorcycles and learned to love speed, however her real love is Formula 1 tunnel-boat racing. These are the guys and gals that are strapped into a tiny cockpit and then hurtle down the straights at 120 mile per hour and pull 5G in the corners. We attended the recent season finale in Lake Havasu and watched our friend Mike Quindazzi try to take the win. Val chats with Teejay about her love for two-wheels and tunnel-boats. Yeah, it’s crazy stuff.
From all of us here at Ultimate Motorcycling, we hope you enjoy this episode and have a great Thanksgiving Holiday!
