 Optimal Setup for Dirt and Supermoto

PostSubject: Optimal Setup for Dirt and Supermoto   Thu Apr 12, 2018 5:14 pm

I have a 2016 WRR and just picked up a SM wheel set (Warp9 120/70/17 and 140/70/17). My off road tires are stock. The bike only has about 250 miles on it. I am currently running 14t/49t for my off-road set up. I like it a lot better than stock for 50/50 riding and seem to have more useable gears for everything.

I want to be able to make the quickest changes between wheel sets. Considering chain, optimal gearing, etc, what is my best setup to make changes easiest.  While I'd like to keep the 14t front, I can go back down to 13t.  Of course, I don't want to be changing the front sprocket.  I'm willing to push the gearing for off road more toward off road now that I have the SM wheel set. The SM rear currently has a 44t sprocket.

Has anyone found the quickest process? What am I missing?

I'm planning to trim the fork covers and use caliper relocation bracket, but the SM wheels have not arrived yet.

Thank you!

I also picked up a set of warp9s for mine last year.

Your best bet for quickest change is to have the same size or 1 tooth off of your dirt sprocket. Depends on the type of street driving you do. I don't ride on the highway so losing some of the top end of speed and picking up some peppiness isn't an issue for me.

You don't need a caliper relocation bracket - assuming your warp9 wheel has same size rotor (mine does)

Pick up a chain alignment tool and you can get your wheel changes down to about 20m.

** Even after getting the hassle down to only 20m I still never use my SM wheels. There's just something freeing about being able to leave the road and go explore in a moment's notice

The stock gearing for the WRR is 13/43, so your 14/49 gearing is about 6% shorter.

The stock gearing for the WRX is 13/42, so if you want to keep the same ratio in your SM setup, then you should get a 48 rear to go with the 14 front.
