Final Drive Ratio

[Bennojammin]

Hello All: Just bought a 2013 Bonneville T100. The chain is sloppy with no more adjustment room and I want to replace it with a Triumph OEM chain and sprocket kit.
The manual lists the final drive ratio as 2.39:1 (18/43).
The kit, p/n T2017230 has a 104 link chain and a 43 tooth rear sprocket, which match the manual, BUT has an 18 tooth front sprocket. This would result in a final drive ratio of 2.53:1 (17/43). About a 6% difference.

Do I care? I've been riding off and on for 50 years, and this is my first "big street" bike. Not anticipating doing a lot of highway riding.

Thanks in advance,
Ben

Is it in good enough shape to take a link and keep going for a while?

If not doing a lot of hiway work the 17/ 43 would probably be best for you . Both of my Triumphs have been moved up from 16 to 17 tooth fronts , 6 per cent is not a huge jump.

Thanks. Since the bike is new to me, I want to bring it up to spec. The PO was a rider, but not much on record-keeping or maintenance. I appreciate your response, Ben

Thanks. Upon further consideration, I think the 6% jump in gear ratio will be a good thing. I appreciate your response, Ben
