Rbike,
My 2013 CB11 has a 19 tooth front and 37 tooth rear and it took my 70mph rpm from 4000 down to 3600 and made riding much more pleasurable. The speed limit here in AZ is 75mph. Starting out in 1st gear is no problem even when two up. If you go all the way down to a 35 tooth rear you will need to break and shorten your link-less chain and you'll need to see how much the chain drags on it's slider. Taking a link out of the chain is not necessary with the 19/37 combination. One other item to look for. The stock CB11 rear sprocket is steel and very durable. Almost all aftermarket sprockets are made of aluminum and wear out much faster. "7th Gear Designs" has made custom 37 tooth steel sprockets for several members here and they are a work of art with slotted lightning holes. They are the company to contact to make you a steel rear sprocket.
When you finish let us know how it works out. All the best bro.
