Check this forum history! If I'm recalling correctly, that there is an issue with Xciting sliders (exploding variators). I believe the consensus was to stick with stock rollers in this machine.
Also, for what it is worth, once I get to 90mph, I don't like it.
1.) This speed makes me nervous and increases the risk of an accident.
2.) RPM's are high at this speed and I don't think it is worth the possible damage to the engine. 75mph is about the top I will run (interstate only).
The technical top speed of the engine on the xciting500 is about 97 mph. It's there for a reason. Not to stay there for extended periods of time but to use it when it is needed. I generally cruise at about 75-85 mph because on the California freeway system it's actually dangerous to drive slower than it is to drive faster sometimes.
You can get mowed down by a frantic Los Angeles Driver who has no regard for your presence. I am not saying all of them are like this, or even half of them. But there is certainly a number of them like this.
What city do you reside in, Sir?
