If you do tell me about speedometer accuracy and/or any other pro's or con's before I take the plunge. Thanks

stock to stock, the 1300 final will put your speedo 10%ish off... go with a tire that's got a smaller diameter than stock and you will go even further away from accurate, add a taller than stock tire and it will bring you closer to accurate.

Stab in the dark would be 1300 final and a 65 series tire would probly be pretty close...

1300 final makes speedo read lower, and with taller tires even lower yet. Mine reads below actual, speedo at 60, I'm doin 70, but my tire's O.D. is 27", on the tall side. Most I've seen post with 1300 finals and 205/55-16's say their speedo's right on, but I'd rather deal with speedo error and run a taller tire. I ride mostly solo with no extra weight so I love my tall gearing, between the 1300 final and the tall tire, my gearing is up there. 45 in 1st gear before the limiter kicks in, and at 80 in 5th the motor sounds like it's on fast idle. If you run a low profile 55 with the 1300 final you lose about half the gearing you've gained from the final, vs. running a stock height tire. A taller tire takes your gearing even higher, but your speedo accuracy suffers, choice depends on your priorities. I believe a 205/65-16, avg. 26.5" O.D., w/1300 final will make speedo read under actual. Most 205/60-16's are the same height as stock 1800 rear MT's, but tire mfgs. vary in the same size, always check their specs to be sure. study

Thanks for the info. Considering what you said I might be inclined to go with a Goodyear Triple Tread 205/60-16 instead of the Michelin Hydroedge 65. All my riding is one up only and cruising the secondary highways instead of interstates. My riding buddy has a Super Glide and that's what we like to do. Just cruise around about 60 most of the time and stay off the super slabs mostly although we kind of planned to go to Tennessee and visit his brother this summer and will hit the interstate most of the way I think. But for what we do the 60 tire might be the better choice.

Sure, middle of the road so to speak, since the speedo reads high stock, with 1300 gears your speedo should be closer to accurate, and you'll gain the same gearing advantage from the final as with the stock tire.

I notice you are using a Toyo 215/45/18. That would account for the big difference compared to a stock 16 inch as I understand it. I'm leaning toward the GY Triple Tread 205/60-16 but I'd be interested to know where it would stand using a 195/55-16 too. It might totally negate the 1300 rear end advantages though but I don't know for sure. I looked at some 205/60's and those suckers look like they are pretty wide and tall compared to the stock tire but a lot of guys are using them.

My 1300 final is on its way! I found a great guy down south to swap me even for my 1800 final. I'm sticking with the 205/60/16 right now. There are so many better tire choices in a 55 profile but I am trying to keep my pegs off the road and the gap between the fender and tire minimal. I may even try a 65 profile in the future.... Man, that would sure give me some long legs!

I have been checking out pics of you guys who are running lower profile tires, and they look fine. But how low can you corner compared to a 60 or 65 series? I know its only an inch difference between profiles, but on an X that inch can make a world of differance.

Looking forward to feedback and opinions!
