Rear sprocket

[molokaimike]

Since I'm changing out the rear end on my TG I was playing with the idea of going to a smaller rear sprocket. The thought being to lower the RPM when at highway speeds. My concern is going with too small of a sprocket which would mean that I also need a shorter belt. I currently have a 70 tooth rear sprocket and was thinking of changing to a 68. Any thoughts.

I dunno Mike, that might gear you a bit too high?

On my Electra Glide Ultra I was spinning 3K at 80 MPH on the highway, with the TG I'm spinning 3400. The Ultra had a 68T rear sprocket so I'm thinking that going back to that would lower my RPM. At 3400 my gas mileage is in the high 20s.

You might have to feather the cluch a little to drive off from a dead start if your Geared too high.....:Shrug:....Thats why Harley after 2010 went to a lower ratio on the Tri-Glides ...

My fix is changing height of tires going to 70 series and possibly75 series more feasible way to mess with gearing. Also different brands have different diameters just a thought keep us posted Fred

Thanks for the idea Fred. If I had to back to stock it would be a lot easier changing tires as opposed to taking the rear end apart to change the sprocket.

Also the little bit of height gained by the tires really planted the front tire. Our trike handles so nice. It was a bonus to the gearing that was not expected . Travel safe Fred

Would changing rear tires work for a 2016 Tri-Glide too and if so what size of tire?

I do have a lift kit and pro- action shocks from DK Customs on my trike.

Take a look at your tires, if they're a 65 series like mine then a 70 or 75 series tire would add some height. I would measure your tire height then compare that to the height of a 70 or 75 series and decide how high you want to go.

Go to a tire comparator chart that is what I did there is a lot of room for tire diameter just not wider. Look at the distance per revolution. Fred

Just a thought my speedo is 2 mph slow now with 70 series tires on. they role just a little farther each time.

I had to recalibrate my speedo when I switched to a six speed tranny on one of my older bikes. I bought a unit that plugged into the wire harness that had a button which would adjust the needle while you were riding to the correct MPH. You needed someone riding next to you at a fixed speed then you would adjust your speedo to match it. This was back before hand held GPS was around. Can't remember where I got from.
