Is the S40 suitable for group riding?

As long as you realize group rides are some of the most dangerous rides you can do on a motorcycle.   Google it and be safe out there!

get the details on the group ride before showing up. The sport bikes like to take really technical routes at an uncomfortable rate of speed. Some of the cruiser rides buster down the freeway at 90 mph. Best to find out ahead of time.

Absolutely. I have no problem going with Harley guys and sport bike guys, easily keep up with my friends with MT-10s and R1s. The S40 is so light and agile, it handles tight twisties better than heavier sport bikes.

Of course you wont be able to keep up with sport bikes on fast highway runs, but its made to carve mountain roads all day long.

I was lucky. The only group ride I've been in, I was at the Very back. For me, trying to ride close to people was just not what I've been doing. I ride looking for separation from traffic. If you've never done it, you might be happier at the back.
Sharing a lane is uncomfortable. Trying to maintain That position, if you're staggering or sharing,, Naaah, not what I practice when I'm out hitting country roads.
I'm glad I went, it was very different, stopped in cool places, had some live music at the BBQ joint out in the boonies for lunch, great day.

Yup obviously, S40 is the best choice for both solo and group traveling, also can perform well in normal commuting and for highways as well.

I’ll admit it’s fun for maybe half hour , it doesn’t take long to know it’s way more dangerous than it is fun. No more than 5 riders that have decades of riding skills not just years. Then I can relaxe and ride. I study other riders habits so I can mingle in the pack if I choose , fall behind see how everyone rides who is aggressive. I prefer to pick my way thru the pack like a gentleman , slide by with what looks like no effort , maybe a nod or a wave just out for a Sunday ride kinda thing. It’s fun to get out in front and run , but I can do that riding alone. Pick your way to the front for a few turns then let them slide by , study my victims some more , then back to the front. This keeps all involved in the ride and everyone gets to pass and be passed making all involved more at home in a pack and a better riders . Also keeps me sharp and hones the passing skills , exactly when to strike , pass inside , pass outside , speed , brakes naw. Don’t forget the nod or wave , manners is everything be polite. Practice this you & your friends will become better , safer , polite riders. I can pass everyone but that only 3 or 4 passes , I would rather practice passing doing 10-20-30 passes in a ride.
Way more fun when you learn good safe passing skills
