Well heres my 2 cents.
I got a chance to test drive both the street and the bonnie.
The street certainly feels powerful and fast, but its brakes lack punch. I'm no speedster, but a fast bike with "drum like" braking is definitely a No. The wirings isnt much of a concern for me, but the hard compound mrf zappers are, they aren't grippy against concrete road especially in the rains. On tar roads I'm sure they will do fine. Suspension on the bike is definitely great especially when u have potholes the size of crators. Looks is great, but would look small for a person with a more broader figure. Glad im only 5'8''. Build quality is average and although the bike isnt gonna crumble while driving, its certainly not expected from the Harley clan.
In any case, I was planning on booking the 750, but with flaws and lack of thought in terms of safety, I've taken a step back. Once Harley does look into it, i'll prolly book one.
Btw somehow I feel the folks at harley really dont know much or are trying to just sell. One of the folks there told me that they are gonna fit michelin tyres in a yr (post sharing my feedback), while another said there is no such news.
Now the bonnie, im not exactly a classic bike fan, but when I drove the bonnie, it was like a 15 min peak I to heaven. It is very refined, with no vibrations, excellent build with a nice throaty purr. Brakes are far better and the tyres too, metzeler. Torque is on the higher side, could easily go as low as 45...50 and still accelerate on 5th gear. The 750 did have trouble in the 3rd gear. The price however is a bummer. Here in India it costs more, but if harley do not put their act together, im jumping on the bonnie.
Btw drove the iron 883 as well, looks harleys wins hands down. Unfortunately thats their only win.
