when my GSA had some work done on it
Bahnstormers gave me a lovely RT to ride home on
i found that you get the opposite effect to the problems with the GSA for short people
where tall lanky people like me self are very suited to the GSA ie very comfortable and can sit flat footed
the RT is the exact opposite - yes i can sit flat footed but have a good look at that tank - where it goes up at the sides then sort of bulges out quite sharply at the top - i found that my legs wont fit under the crease ther fore i was riding with my legs much wider open and it became quite uncomfortable
the second odd thing was where the frame is wider at the back where the gear change is than the front i was riding pigeon footed - ie my heal was forced out by the frame and the front of my foot was pointing in - this coupled with my knees being forced to stay outside the top of the tank made the ride very uncomfortable for a lanky git like me
but if you are the right build you will love it - its a lovely comfortable fast quiet and smooth bike
now on the other hand i am looking forward to a try on the new 1600
