Is the difference in sprocket size due to the DCT/ABS model and tire size?
No, tire size is the same, for some reason, the primary reduction (between the crankshaft and the transmission) is different on the two models. The DCT has a numerically higher primary reduction and a numerically lower final (sprockets) reduction. When you multiply the primary reduction times the final reduction, you get an almost identical overall ratio with the DCT being lightly higher numerically (4.68 for the DCT vs. 4.65 for the manual).

And ABS is standard. Just now doing a little more research. thanks

I don't know what you mean by "ABS is standard". ABS with linked brakes is only offered in the US market with the DCT transmission. the manual transmission is not available with ABS and does not have linked brakes.

Standard on the DCT model as you mentioned.

I'll shut up now.

If you want ABS only, in Canada, it's sold with ABS but without DCT..

Honda Canada also sells the NC700S, also with ABS only.

Geebus effing keerist, would someone please punt the ABS rabbit trail off into the nearest oil thread? If I want to hear religious opinions on ABS I'll go look for a thread covering it.

I don't understand these posts about ABS. According to my Milliken and Milliken book for racecar vehicle dynamics, optimum wheel tractive force both laterally and longitudinally is found with a slip ratio of 17-25%. Abs and traction control aim for these values to reduce stopping distance by controlling slip ratios determined by angular velocities of each wheel. So unless you're offroading, I completely disagree with the above statements.

I use 26.6789234567% when braking manually. No wonder ABS is crap. Maybe it's my 10.23689746 millisecond response time as well.

By the way, some ABS systems work well off road up to a fairly high limit. No one wants to believe that yet. Wonder what this one's like?

Current ABS systems work by cycling between virtually no slip and lockup, not by feathering to perfectly optimal slip ratios.

but it gives two example of of what a bike with linked brakes does, without abs.

Really, I don't notice at higher speeds in gravel, but when the speed gets a bit low I do. Are you sure that is the case at all speeds. It seems awfully smooth above about 15Km/h apart from that grindy thing happening.

All current ABS systems work by cycling. How often and how close they can keep a wheel to optimal traction? That's where the better systems do better. (I have no idea about the NC700X system in particular.)

I would ASSUME it's a carry over from a previous system. But at least it's there if you want it. Will have to wait and see after some gnarly dirt action I suppose.

So if that is the case it would be like Pulse width modulation. The more pulses the smoother it seems. Time to get a slo mo camera me thinks.

Brad, they didn't quit.

While waiting on my moto inspection to come through at the local dealership, they had a NC700X. I sat on it. Very upright position. Not much to that windshield. Or the front end at all. Seemed pretty nice, though.
