I know this thread is super old but oh well
I have gone 125 for about 30 sec - 1 minute or so a couple good times on a clear highway. Yeah I know its not safe, but I am a hooligan sometimes. ATGATT everytime though. I come from sport bikes, so going that speed is comfortable for me lol I am in Florida though so Florida's sea level does allow me for higher top speed if I am not mistaken. I have K&N filter w/ kuryakyn air cleaner, two brothers 2 into 1 full exhaust, and cobra powerpro black w/ Pirelli night dragon tires and I weigh 220. Handling feels solid the whole way to me
