I went with the "full meal deal" with Tru-trak.
When I had my mishap recently (oldtimers I think) the bike did great, but I have been tinking. It took a pretty good lick and when we got it back on the road it was like nothing happend.
I would speculate the all of the Tru-trak stuff including the metal bushing etc. had to have added to the bikes ability to withstand the tossing and twisting it went through going down. Specualtion I admit, but I have gone 500 miles or so since the mishap and it is straight and true as before.
I don't have a good comparison of just the Tru-trak add since I also did the Traxxion forks and 440's at the same time, but I know these are all mods I will do on any new bagger I get, based on the improved handling of the bike after the mods. Now if the rider could keep up with the bike I'd be in great shape.
