In the past few days I’ve had a terrific email exchange with Bob from Tilting Motor Works. His company has developed a fascinating kit to convert essentially any standard motorcycle into a leaning tadpole trike. But more importantly, he’s done over 10,000 miles of real world road testing on his tilting suspension design. I asked him if directly linking the shocks to each other had any adverse effect on handling. Specifically, I wondered if hitting bumps while leaning or in other tricky positions would give the vehicle any proclivity to change course suddenly or alter its tilt. This was his response:
Yes, the force can be transfered directly to the other wheel but my experience shows me that it is no issue even while cornering or going over railroad tracks. Actually all suspensions ultimately transfer the force to the other wheels, just not as directly. I tested my suspension by laying 2×4’s all around my cul-de-sac and running over them at different speeds and angles. The bike performed great.
This is such great news! A front suspension setup similar to what Bob’s developed seems the perfect match for Project Streetliner, but I didn’t know how capable that kind of dampening really was. I also asked Bob about comfort and he was happy to report that his front end is far more comfortable than stock and that his VMax prototype is always his first choice in a stable of fun vehicles. He’s graciously offered his time and expertise and I’ll be giving him a call very soon. Thanks, Bob!
