I didn't get an opportunity to ride any other bikes. I took a leap of faith on the SR/F, but that was mainly due to logistics. I wanted to ride the SS9, but never did just because it didn't seem like a good purchasing decision if something were to go wrong with the bike.
There were enough videos out there that I had a pretty good idea that there would be things I wouldn't like about either bike.
I did sit on a SR - and to me it felt like a toy. Not quite a Grom, but still just didn't feel right. Was pretty convinced I was buying an FX or FXS until they announced the SR/F.
I thought the headlight and the little bug catcher windscreen on the premium would really bother me. I was convinced I'd replace it with a round headlight. But once I got the bike, it grew on me pretty fast. There are still some cosmetic modifications I'd like to make. But a lot of the things other people don't seem to like - I'm absolutely fine with.
Some of the stuff Sam says I loosely agree with, but some of it is kind of silly. First, it doesn't look anything like a gas bike. I park next to a Ducati Monster at work sometimes. Probably the ICE bike that looks closest to the SR/F - and you absolutely can't mistake the two. The SR/F doesn't look like a gas bike from any angle but maybe the front. I think the SS9 looks more like a gas bike than the SR/F does. The tank size is fine to me. And the bike overall seems fine. I'm 42, 6'0 and 250. I'm not the most flexible person, but I don't have an issue with where the pegs are at all. I generally find the sitting position and posture on the bike comfortable. I don't hurt or anything after riding it for a few hours. Not sure why he's tilted about the door over the charge connector. I don't feel like the bike is heavy, it seems like its pretty flickable to me. But - I'm not a connoisseur. I haven't ridden a ton of different bikes. I've seen a lot of reviewers complain about the suspension stiffness - I prefer a firmer ride so I think the suspension is great. To me - the bike as a whole is just really well done. I'm also in an area where CCS isn't a thing yet. While I do wish the charging capabilities were better, the SR/F is by no means an unusable bike. For 99% of what I'd use a motorcycle for, it can do it.
There are some things I wish were different... but i've kind of said before that I wasn't planning on keeping this forever. And even if I do keep it, i'd likely be looking at another e-bike in a few years when we get a generation or two out on batteries and get to whatever the next gen charging tech is.
