While I’ve only ridden the Zero DSR and SR/F, from what I’ve read in other reviews, the Energicas tend to run louder due mainly to the chain final drive and other mechanical bits.
Personally I felt the Zero’s were extremely quiet when compared to my Triumph Trophy’s stock exhaust which is one of the quietest ICE bikes I’ve ridden in 20 years.
Even watching a few co-workers ride their Zeros (DSRs and SRs) into the office parking lot they were quieter than the crap load of Teslas our office has in the parking lots.
Yeah, I know all EV produce sounds coming from different sources. Heck, I usually rent Segways when vacationing in Europe and even them, with a maximum speed of 12 mph, make some noise when compared to a electric bicycle.
Part of it, I believe, is having a high torque.
I just thought the SR/F, while going steady at say 25/30 mph on a flat road, would make less noise but I am not complaining, just trying to determine if it is normal.
After all, I got a dealer demo and it could be different on the production units.
By the way, I got an OTA firmware update (cool
feature) couple of days after I received the bike and brake regeneration sound is slightly different -using always the same Ride Mode- but other than that, I don't feel any difference.
