Get ABS, without any question get ABS.
ABS won't ruin the ride or the feel and 99% of the time you won't need it. The 1% of the time you will need it, you'll be very thankful that you have it. I doubt you’ll do much, if any, off-roading even if you do I’d still rather have it.
There is a reason its fitted, its fitted for your safety. As the good book states, sacrifice anything for safety but don’t sacrifice safety for anything.
As a new rider on a ‘proper’ bike, you’ll be experimenting with grip in corners and braking. ABS could save you loads of grief (and repair bills). If the ABS comes on, you’ve got it wrong, learn from it and brake earlier or slow down. I wish they did it on the 1000 cos I’d have it any day.
