Remember, it has been found that using ODD/ODD or EVEN/EVEN combinations of front and rear sprocket will cause your chain to wear faster than using an ODD/EVEN combination.  Oring chains are wider etc than the old school non oring chains.  I have found it difficult to install a 16 tooth front sprocket on early roundcases [sandcast engines] using an oring chain.

My favourite combination is a 16/39 on my Darmah.  However, I stock both 15 and 16 tooth front sprockets as well as 36, 37, 38 and 39 tooth rear sprockets in order to offer the widest combinations that are more useful today.  Remember, tall gearing was installed to keep the revvs down to help pass DOT noise restrictions etc...  I prefer to get a better jump off the line, this helps around town riding etc as you never want to lug the engine.

What is Titan Tough?  it is a super hard anodizing put on aluminum sprockets that makes it wear like a steel one.  You get lightness, long lasting and a nice colour.  The Titan Tough hard coating has a dark look to it [almost black] - You can also get your sprocket done in different colours.
