Better stay with original front sprocket
There were a small freeplay on the coutershaft when installed and torqued it. I installed it with grease on the countershaft to eleminate wear. After 10 000km i notice the coutershaft was wear out by the sprocket. I ordered a original OEM honda front sprocket and the quality control is 100% better with no freeplay when installed. Never cheap out on aftermarket sprocket it can cost you a 400$ countershaft at the end.

The cushioning may make it last longer
I've had OEM cushioned drive sprockets on some of my bikes, I'm assuming it's easier on the driveline and in my experience these seem to last longer, the OEM on the other application lasted 50K. I certainly never got that kind of K's out of non cushioned sprockets.

This was a perfect replacement; first time with the cushioned option so will see how that works in the long run.

Questions
Item 645-400. Is this sprocket a 520 or a 525 pitch
Pitch depends on the vehicle. Simply enter the year, make and model of your bike on the product page to check fitment. The correct sprocket (with correct pitch) will then be recommended for your bike. In some case, you may have a choice between pitch sizes from the options list, if a conversion is available for that model.

Is this sprocket a direct replacment for the stock OEM sprocket requiring no shims or other adjustments to install correctly?
Mine bolted right up on my 2000 vfr800, only have about 50 km on it so far so can't say how well it will hold up.
