Being able to talk between bikes is a whole other world. The reason I got mine in the first place....buddy accelerated on to a major highway with a long rope trailing, could not catch him or warn him till he laid off the throttle at 70+ merging into busy traffic.
Could have been bad news.
Got Scalas the next day.
When my son and I rode out west for 3 weeks we'd have the lead rider keeping an eye on road conditions while the trail rider navigated and relayed up coming turns etc.
So easy to discuss fuel stops, are you hungry ...what should we have for supper, how is your *** doing.
In his case since he's diabetic he needed to stop fairly often so easy to let me know why .....
In the twists we'd set up a distance so he could boogie ....see ya 10km ahead etc.
If I wanted to stop for a photo I could tell him so he knew it was not a bike issue ...he'd continue on and let me catch up.
In some cases it allowed us to pass safely on blind curves - he had far more power than my heavily loaded Vstrom so would get ahead and then let me know when the road was clear....I'm sure we gave a few drivers fits
