People coming off or 2 wheels typically think the Spyder/Ryker to be 'Twitchy'. This is because they are used to the extended amount of time it takes for 2 wheels to translate handlebar input to a change in direction. Small inputs to the handlebars on 2 wheels are completely absorbed with no real effect on direction. The 2 wheel brain builds all of this into expectations. So, when you get on a Spyder/Ryker, where every (even the smallest) handlebar input is instantly transmitted to the pavement. The 2 wheel brain interprets this to be an uncontrollable, twitchy machine. When in reality, it is simply very responsive. This has dissuaded many potential buyers. Yet, it isn't the vehicles fault.
People then, in an attempt to stabilize the Spyder/Ryker, will tend to stiff arm the handlebars. Which makes the problem worse. Instead, you need to relax your grip, relax your wrists, forearm, etc. What you want to achieve is an isolation of input from your body movement from affecting the handlebars, and hence, steering input.
Next, 2 wheel riders are not accustomed to the left/right movement from 2 outlying wheels on an uneven roadway. 2 inline wheels don't see these anomalies. So, it isn't an issue for them. Nor, is it an issue with the Spyder/Ryker. But again, it bothers the 2 wheel brain. It's simply a different machine which requires a different approach to riding. After awhile, you don't even notice the slight left/right tilts from uneven road surfaces. With a little time in saddle and practice, you'll find the Spyder/Ryker the most stable motorcycle possible.
For me it took about 600 miles of riding the Spyder to get over this hump.
People not accustomed to 2 wheel motorcycles can get on a Spyder/Ryker and hit the freeway with no issues. I've seen it done. They have no 2 wheel mental baggage that they have to deal with.
Yep, that was me. Been riding two wheelers all my life (since about 14) and never rode a three wheeler. When I first rode the Ryker I thought, what the hell. But I bought it anyway and figured that I had a learning curve to go through. I had already done pre purchase research here and at other sites, so I knew about the sway bar and end links. I put your end links on and it helped a lot with that twitchy feeling (thank you very much). Also, just like on bikes, increasing the tire pressures by 2 or 3 psi above recommended, also improved the ride and handling. Being in Florida (all straight roads with very little or no curvy roads), I've been happy with the end link improvement and didnt feel the need for the whole sway bar kit. Id imagine if I was riding curvy mountain roads, the upgraded sway bar would help greatly with keeping those front wheels planted a little firmer.
Within the first hundred or so miles, I discovered that with that relaxed grip, the bike quickly corrects itself whenever running over irregularities in the road. So there is definitely a learning curve for two wheel riders with these machines, and once you get it, its as much fun if not more fun than the two wheelers, its definitely a more relaxed ride for me. I've kept one of my bikes just to be able to scratch that two wheel itch every now and then, but 7 months later I find myself enjoying the Ryker more & more and hardly riding the bike. As a matter of fact, I just got back from taking the bike out on a 40 miler because its been sitting for about three weeks without any run time.
