I have an '07 V-Strom 650. I want to put on a 16T front sprocket, however I'm having some doubts. I know that everyone has said it is wonderful when on the street. I have no doubt it will do just fine when riding around solo and 2-up. My problem is... Will it be too tall for when 2-up touring with all our gear??? The weight should go something like this..... Combined 2 people plus riding gear - ~ 360lbs Camping gear and clothes - ~45 Tools - ~15 So figure once riding we will have about 420 - 430 pounds on the bike. I've raised the rear by 1 inch so I'm not worried about clearance. I'm worried that the 16/47 ratio versus the 15/47 ratio will be too tall? It would bring the RPM's down by 500 so it would be 5500 rpm's at 75 vs. 6000 at 75. I'm also wondering how it will affect gas mileage when fully loaded 2-up? Would it be so tall that the more effort at speed would actually use more gas, rather than less? Any input on this?
