what it all boils down to is the fact that we all bought a "hotrod" bike. the temptation to open it up is hard to overcome just for the simple enjoyment of doing so. therein lies the problem. twisting the throttle= tire wear. if you want to save the rear tire you will have to go with a cookie cutter with less power.
Attention: I think this is a scam. The regular air they use to fill your tire is already 78% nitrogen. Regardless, a nitrogen atom weighs 14 units whereas an oxygen atom weighs 15.9 units, a miniscule difference. If you look at the advertisement pamphlet for nitrogen filled tires, it shows the nitrogen staying in the tire whereas air leaves the tire faster. In actuality, nitrogen is smaller and moves faster than oxygen and therefore will leave faster. Save your money.On the flip side of the coin. I have had good results using "nitrogen" in my motorcycle tires. I do not do burn outs, try not to brake hard, but I am guilty of high speed riding. I now have 6,000 miles on a Avon Venom with an easy 3,000 more to go. Twenty bucks for the first tire purge, and a years worth of tire top offs @ once a month.
i agree,the cobras suck balls! the first 2 venoms i had went 12k each time.my 1st cobra barely made it 8k and the one i have now is on the wear bars at 5k they are using a shitty compound for these cobras,what sucks is i havent heard much better out of the metzlers or i would try oneI agree for the most part, but doesn't help any when a tire company makes a lesser product and fail to acknowledge it. The new Avon's cobra's are shit compared to the venom's of the past (or did I mix that up). I don't hot rod my bike "much" and put on a lot of highway miles. I shouldn't be seeing wear bars at 3,500 miles. I used to get 10 - 15k out of the old ones.
Hmmm. Atomic weight aside, the biggest virtue to pure Nitrogen lies in its lack of expansion when heated. Your cold vs. hot running pressure is not going to change like it will with air and the moisture air carries. It's why we run it on the track. An air filled race tire will increase in tire pressure as much as 20-25 percent from ambient once up to temp. Where a Nitrogen filled tire will remain virtually the same. Not a huge deal with a road tire (why I don't bother). Road tires aren't going to take on the same brutal temp change, but a couple pounds pressure still will happen. So not terribly important on a cruiser. But I wouldn't call it a scam.Attention: I think this is a scam. The regular air they use to fill your tire is already 78% nitrogen.

Scam or not, to each his own. What I do know is that after 4 plus months, my tires only needed 2 pounds in one tire, & only one pound in the other. NEVER had that with pump air! Twenty Bucks, shit, I've wasted more than that at a bike night. Gives me piece of mind.Attention: I think this is a scam. The regular air they use to fill your tire is already 78% nitrogen.
