Hi,

I was wondering if the 690SMC will be fast and agile enough on a tight track? Or is the 690SMC too heavy?

And if he is usable on a track, could the 690SMC keep up with a Husqvarna 510smr or a berg?

I haven't ridden the SMC but I did ride a 690SM. It was remarkably similar to my 560 in terms of feel, except for the weight. In plain english though my 560 would chew it up and spit it back out at the track, with equal riders. My guess is that so would the 510 since it is also a race bike. I have no experience with 'Bergs so I can't say.
But for real world riding on the street the 690 would be, by far, the superior ride.
