One of the secondary ratios is slightly different, 34/36 vs 35/37 and if you factor all the ratios together, you get 22.1418 for the 2016 and 25.5023 for the 2013. That is slightly more than 15% lower RPM for the 2016 in top gear. The final drive gear swap can get an 11.1% reduction in RPM for the earlier models, but the 2016 would still turn about 4% slower. Definitely a tall gear ratio.</p></blockquote>
<br />
^^ True, but have you calculated the RPM reduction when going up to a 190/55 rear tire? Before modifying the final drive I found the 190/55 tire stepped up the speedo reading 2 MPH which made the speedo match the mph on the GPS.</p></blockquote>
<br />
Going to a 190 rear tire gets a calculated 1.75% drop in RPM and maybe a bit more since it pinches the tire cross section a bit, so with all the above, the six speed tranny is still revs slower by around 2%.</p></blockquote>

I can live with the "around 2%" difference. $300 final drive mod. is a no brainer vs buying a 2016 bike. </p></blockquote>
Ditto.
Just added the Venture gear to my 05 and would say that this gearing is what the factory should have installed.
Excellent upgrade.
