I have the twenty dollar special on the Boss Hoss and its been there for years. Doesn't compare at all with the electronic cruise but then again its simple, it works -- kinda, and its really an unnecessary luxury anyway, not to mention it was **** near free. I think Triumph should put it on at the factory, at least on the touring models, it would only increase the cost a few hundred bucks.
On a temporary short time basis, I use my Go Cruise 2 for stretching out my right arm/shoulder and scratching itches.
The lock position also allows easy movement of the throttle and reduces wrist fatigue from spring tension on long slab rides.
