Speedy & The Spyder (A lightweight sporty build)

sheath · 2025-04-20T20:18:44Z

I've had this idea to build a rig that would travel easily in a smaller Toy Hauler travel trailer. Something smaller, lighter and "zippy". With enough oomph to run 65-ish through the mountain roads, while not being afraid of gentle forest service roads. Was able to pick up a smoking good deal on a '79 Motorvation Spyder T1, and an almost new Triumph Speed 400. The Spyder is a restoration from a member on ADVRider. Here is the thread where he did all the great work: Really excited to pick this up. 🤩 Not sure how this will work out. Please keep your paws crossed for success. The bike is small, and the Spyder is about the max weight and size. But if it does the pairing should look pretty great. Proper design for the setup will be critical. The subframe is going to take some real thought as the Triumph uses a hybrid chassis. *** Edit to add: Short cut to the second test ride with thoughts for those who don't want to read through 11 pages of my drivel. Also changed the title to better reflect how it actually came out. ***** The enticement for the bike is all the reviewers stating it is "... under-geared, with great mid range power." Also the reviewers like the quick easy turn in with the 17" wheels. The sidecar was a choice between this Spyder or a California Friendship 1. The CF-1 is about 40lbs lighter, and may have been an easier mating. But the Spyder is sexy, with the link suspension and a slightly smaller body that matches the size off the bike better. There is a whole lot that has to be done to both, and the goal is to be done by next spring. Info on the Motorvation Sidecar company including the Spyder T1:Thought this was a pretty balanced review of the bike:

This ride reinforced the fun of the bike. It is definitely worthy 0f considering a full on but discrete subframe. Need to get the engine swap done on the BMW first, then will investigate the idea further. 😎

Hold my keyboard and watch this! 🙃
