2. Well,if you read my post,I was talking about ALUMINUM sprockets making a $159 Ti sprocket economically feasable and specifically said that it doesn't make sense to a steel sprocket user. Guys that purchase Alum sprockets care about weight savings. BTW most people only change gear ratio once.
3. I mentioned front sprockets to agree that $89 was way too much since fronts don't "seem" to wear out.
4. then why fuck with it? I was merely illustrating that running your bike at higher rpm can have adverse effects which include; lower gas mileage, increased engine wear,increased vibration,inacurate speedometer,confused engine/fuel mapping,etc. Like I said,I ride my bike all the time in various capacities and don't want to narrow it's focus further by modifying the gear ratios.
The engineers spend hours,days,weeks developing the trans,engine control computer and gearing to find an all around good working compromise. For example,an engine might have a definitive rise in vibration at 7000 pm. So the designers set the trans and gearing so that at 70 mph the engine spins at let's say 6500 rpm in 6th gear thus avoiding dead hands and feet after a freeway jaunt. After you installed sprockets with two more teeth in the rear and one less in the front. It spins at 8500 70mph in 6th gear. Now you have sleeping hands and you've lost 5mpg in fuel economy. Yea it's real smart to set your bike up for that one in a hundred rides "Veyron" race and sacrifice your day to day comfort and over all capabilities. Sure.

just my two cents- most guys that really care about the weight savings of a aluminum sprocket are also guys that make gearing changes more often than a commuter guy. those are also usually the same guys that add a slip on, then a full sys, pc, stacks, etc etc. at each modification step, the bike makes more power, and/or the powerband changes, so if you had the perfect ratio when you started-now you need to change it. i dont know how sprocket changes mess with your mapping tho. could be true, but dont make sense. and you missed the one reason that negates the reasons you mentioned-more horsepower! lol
veyrons are sweet, but its more like a 1 in 10000 ride, an anyway i think it was a joke. as far as the dead hands thing-speed limits vary, and are rarely payed attn to as riders are usually more concerned with the flow of traffic. for instance, in a cycle world test of a new bike, they found that right at the cruising speed of 70mph-the engine was in its "really buzzy" spot. guess the designers fell asleep that time lol-and thats not the first time thats happened
you say you dont want to narrow its focus-but actually by changing sprockets based on what you're doing-you can maximize your bikes potential at the track, canyon, stunting, commute and dragstrip. sprocket change takes like 15-20min, lift it up, chain adj's, axle, 6-8nuts, reverse process done deal.
im not gonna comment on the ti sprocket for my personal use, like i already mentioned, as the engine makes more power, the gear ratio needs to change. plus i like to experiment.
