robertaccio 406 Posted August 24, 2012 Brad, Colby is the KTM "trials" bike guy and Al is the Montesa trials bike rider you are thinking of. I personally dont like those very small front sprockets, prob 12 is as small as I would go with a 520 chain (but thats just me)the factories keep the chain wrap bend radius usually at minimum 13T with 520 chains with some 12T exceptions and availabilities. Looking through my Parts Unlimited catalog it looks like no OEM uses anything under 12 on any of their machines. To me thats an indicator not to. Why not go 12 if you can find one, then work your rear where you want it? Also in the catalog the smallest front among all the brands is 12T. If you are set on going smaller check the manufacturers website (Renthal, Sunstar etc) Are you playing with the 150XC? whats OEM set up? 13/50 right? I would stay 13 and go bigger on the rear 1 tooth rear is like what 2 or 3 up front. Shoot if its 13/52 final try a 53 (i thinks thats all renthal makes for example) Renthal has a 12T Front and 53T rear thats as low as you can go with renthal for example the OEMs dont like the chain wrap radius with smaller than 12T fronts but most keep it safe at minimimum 13T grab the manual and punch in your numbers here and do some math. http://www.gearingcommander.com/ Share this post Link to post Share on other sites

I don't like to go bigger than 50 on the rear although I could bump it to 52 with a new chain. Its just way easier to swap a front sprocket. 12T is not a problem we have put many hours on that setup riding hard. 10 or 11 IS pushing it with the chain radius but it would be cool to get one as a novelty to screw around with and do some trials work. I'm not planning on racing with it. 12/50 for super technical or 13/50 for going fast are my favorite combos. Colby has one so I know they exist and he has put plenty of time on it without a problem so its can't be "that" bad. Will look and see who is making them. Colby has a 10T, I'd probably like to find an 11T. Share this post Link to post Share on other sites
