Hey a Navi Thread!
We purchased one of these a little over a month ago, for the OTD price of $2500 we got it for I'm pretty happy with it.
Out of the box its a bit of a slug but that was pretty easy to fix with a roller weight change (17g stock to 13g doctor pulley sliders), this put it pretty inline with my expectations for stock 110cc scooter performance.
I also shimmed the fixed pulley face out to pick up a little more bottom end which worked a treat, FYI max it can be shimmed without removing the kickstarter mechanism is 1.5 mm and I don't think I would do that as it would compromise the cooling mechanism.
When shimming beyond 1.5 the fan can contact the protective plate for the the kickstarter mechanism as seen here.
Anyway, I hope these keep selling well, at $2500 or below I think they're an excellent value and only require very minimal tweaking to be a decent performer.
I also think they fill a hole in the American scooter market that I haven't heard anyone mention yet, this is a sub 200cc cheap bike with ergonomics that suit larger American riders. Its priced like a 50cc but I don't know of any 50cc bikes that my 6 foot plus friends would be as comfortable on.
Is this a Grom? hell no! Is this a new bike that I'm not afraid to tear apart and mess around with? Totally, and I think that means its a great starting point for many entering the sport or just looking for a smash-around-towner that they aren't worried about scuffing up.
Full disclaimer, I picked this up to develop parts for it, I see a lot of potential so far as we've torn it down.
Sorry if that was a bit of a ramble.
Cheers!
