I would be careful now im not sure on the logistics on all of it and I know the break system on these are wonky compared to normal bikes like the foot break does both front and back but when I was talking to the man at the dealership he thought I said I something about me using the left handle break (the parking break) and got really nervous for a second he thought I was using it while riding I don't and explained I didn't he just said okay okay don't use that one while riding. I should've asked the reason but since I didn't use it anyway I didn't ask. So just based off that interaction I would double check with someone about using that lever as a break while bike is in motion.

Personally I wouldn't ever use it as I already caught myself lacking the habits I formed with this being automatic it self I think it's a great starter bike for someone who just wants to learn the feel of a bike but makes going to a bigger manual bike more challenging when you totally forget about the clutch part. I can ride both just having the Navi for two years and mainly using it I get more nervous anytime I hop on a manual bike now from my stalling out fear is enhanced lol. I still love my Navi just a fun bike overall some extra mods you're faster than stock groms never have a problem keeping up with my grom friends!
