I went with non ABS.
Although I would love to have it for wet riding, where I live ABS is a liability.
All ABS systems have brake release problems when going over bumps. If a bump makes the rear tire lift just a bit the computer thinks it's lifting (stoppie) and releases the brakes in the name of stability.
It's worse in lighter bikes than heavier ones. Having fully adjustable suspension can help but not eliminate this 'feature'. The BMWF800ST is notorious for this and weighs 100 lbs more than the 250. The new Ducati multistrada also exhibits this 'feature' as does the BMW S1000R and many, many others. The best system seems to be that on the CBR1000RR but sadly, that is not what is on the 250R.
The road I commute on has a craptacular 8 or 9 mile section that is a combination of asphalt and concrete. The asphalt is nothing but potholes and alligators. The concrete is buckled up everywhere from tree roots growing underneath. Considering the Honda weights 359 lbs wet (368 for ABS) I can only imagine how long it would take to stop on this road should a deer step out in front of me. And there are lots of deer and other furry critters in my area. I imagine I'd be releasing and re-applying the brake lever (to reset the system) like a mad man.
If the ABS system was switchable I would have gone for it and I DO suggest it for new riders or riders who ride smooth road surfaces all the time.
It's just not a good idea for me and my specific conditions.
any extra reading on this bump issue?
