I may be riding the 07 TW to the Blue Ridge Parkway from indiana and riding the whole thing then back home sometime in October with a friend on a klr. Im guessing around 1500+ miles. Just curious what other experience with 15/47 gearing is? Im a 150lbs and this will be a road only trip "well maybe some gravel" but no real offroading. Im thinking the uphills would be ok in 4th at 55-60. Im running 14/47 now but i do alot of trail riding around here and it will still pull 73-75 mph wide open. I would be changing the gearing once i get back home. Thoughts? Smart arse comments are welcome too!

As one tooth on the front = three on the rear I'm thinking your going too tall. The Blue Ridge does have some long steep grades so I'd stay with the gearing you have and enjoy the ride.

stay with 14/47 the 15/47 wont pull the hills.

BRP speed limit is only 45, and if you have a glorious fall weekend, "leafers" traffic will slow you down even further. Other than the "doing the whole thing" aspect, it's better to enjoy the far more scenic southern end, than rushing to do it all. IMO.

I more concerned about riding the slab on the way there and back trying to run 60-70 with a klr.. I would think it would be better on the hills because you could ring out 4th gear on the uphills and maybe maintain 55ish. I might be crazy though.

My wife and I run the 14/47 combo...... We road it out west in and around the bad lands. You could tell even with that combo the dub didn't like some of those hills... Then we rode from sundance wyo. to the devils tower on some long up hills... I don't think a 15/47 would like that much without lots of 4th gear riding. OMM.

You'll gain nothing in the 60-70mph range with taller gearing. Frankly, 70mph is asking too much from a TW. 60mph, yes, 70mph, no. Simply not enough power no matter what you do with the sprockets. With 15.47, you'll wind out 4th on hills, shift to 5th, and the bike won't run over 50mph. The 3-4 and 4-5 gaps are just too wide. You'll find some hills on the BRP will require 3rd and 35mph wide open.



I've done 700 mile days with 15/54, no problem. If you are running street tires, go 15 or 47, not both, at the most.
