Its slightly better than stock, and yes it can wheelie more but all humans have a handy wheelie control device on the end of their right arms

Its still too tall with 18/45 imo.
The bike feels flat and boring to me with the stock gearing, the 17/43 (very similar to 18/45) was a little better, but still didn't feel like a thousand should, i was still disappointed in the difference from the 675.
Now with 17/45 it actually has proper punch like a big bike should.
