When buying my R1200GS the main reason I didn't go for ABS was the £800 cost. For the same money I was able to get Panniers, Crashbars and other odds and ends. Would have cost me about £20 a month extra in my repayments over five years. I also felt that maintaining the bike without ABS would be simpler and cheaper. I also hoped that I would be able to ride the bike in such a manner as to avoid locking the brakes in the first place and do practice hard braking every now and then. To date I have been very pleased with my non ABS brakes and have found them to be very effective. Just need to keep practicing emergency stops
