Yeppers, much easier (and less expensive) to have cruise w/throttle by wire.
My truck and a friend's HD have TBW. Both act a little sluggish in throttle response compared to a direct 'manual' connection to the TB.
Unclear, but the 'sensitivity' was told to me to be somewhat adjustable on the HD.
Whatever kit you but the install is going to be basically the same you will be stripping the bike all the way down to the throttle bodies then installing from there up this is where you will burn shop time,
The way I see it every kit will need power a speedo feed and a tach feed and most likely a connection to the brake lights I would suggest that both the MC and ROSTRA will do this at the same point on the bike
The MC will have an advantage as the controls will come prewired not a big issue to me as I used OEM the other advantage is that the MC will be or should be pre-configured with correct settings etc this again was not too big of an issue with the Rostra as there is plenty of info out there to reference. The MC should also have pre made brackets etc to replace what the F6B has missing but they are easily made for the Rostra
Both kits will produce the same result if your going to do it yourself I would say go with the ROSTRA just spend some time reading and your be fine
If your going to have a shop do it buy the MC most shops wont deal well with the ROSTRA labor will be the killer I found it easier to remove all the plastic to route wires and cables most shops will want to do this.
For me, and it is only my opinion ~ which only suits me ~ the one and only thing I dislike is the paint quality / lack of clear coat or whatever you call it. Was at a dealer yesterday, looking at a black and a red F6, both 2013s and just from them being dusted / cleaned on the floor their paint was in real bad shape. A casual comment / question about it and the sales guy seemed to take offense, not my intent, but it did kinda end my shopping experience. Guess I'll end up contacting Honda of Russellville and see how much they charge for a repainted black bike!
I never really noticed any paint issues on the bikes I looked at in a few dealerships around here....but, things worked out for me when I bought my F6B as my wife did not like the red or black that was offered...So, we "popped" for the cost of a complete re-paint job, big bucks, and love the color and the nice job that was done...BrandyWine Red Clearcoat....No paint issues so far...Guess this topic should be moved to the paint issues section, sorry.....
