The 7th gear unit is a re - geared bevel drive unit for the C10.  Steve called it the "7th gear unit " because with this unit you don't want to upshift to another gear when you're already in 6th anymore.
From Steve's information:
The 7th gear unit has 12% higher gearing than a stock Concours bevel drive. This means you will run with 12% less rpm per gear per road speed. For instance in 6th gear, rather than 5000rpm = 80mph, you will now only turn 4400 rpm for 80mph. Your exact rpm may vary somewhat due to your choice of tire and size of tire.

highly recommended

Stupid Hurts! Wearing protective gear is much more comfortable.

7th gear  is a bevel gear with a higher tooth count. Just like a 1 tooth bigger front sprocket, it lowers RPM which gives the C10 a more relaxed cruising speed on the High Way.

Hey Steve...after you installed your new jets the added power makes me shift through the gears quite fast. Is that normal and will the "7th gear" mod calm my left ankle?

How difficult is this for a novice such as myself to install?

yes, you'll shift less, everyone remarks that 1st gear becomes actually useable. The 7th gear unit really shines when running long hauls to the twisties.

 While I can't say what an individuals mechanical abilites are without knowing some about them, the 7th gear unit is a plug and play unit that only requires removing the old bevel and bolting the 7th gear unit on. Basic and tools and a day's work. Steve

Yes highly recommended indeed. Really makes a difference with the "buzz" by reducing the RPM's at cruising speed. I am the proud owner of one of the first units also and it is smooth as glass.

This is the single best mod and the best money you will ever spend for your C-10.  I have it along with Steve's cam reset gears and 2 minute mods, for more torque down low.  I find myself shifting less. I can put the bike in 4th gear and go around the backroads all day long, whatever speed I want.  Highway cruising is much less busy, quieter, more relaxed, etc.
