Definetly go the ABS, i have locked my back brake a couple of times , its something i'm very wary of its a big bike a lot of weight and can be easy to do .. Worst one was in the wet with new tyres , I went for a long ride to scrub in some new tyres in the pouring rain , 3 hours later , 2 minuites from home coming up to the lights and it locked i ended up going through a red light and stopped all red faced and embaressed half way through in ther middle of the lights ,
Luck for me the other traffic had seen it all and waited for me to stop , Lucky not all car drivers are on the phone and doing there nails .
Would'nt make me sell my rt3 , but its the only bike its ever happenned to me on and when i replace it i will make sure that the next one has ABS ,, its a useful tool , ,,,,when you need it ,,,
