90% of the time it's rider, but I'm afraid that's a serious 10% remaining on equipment. Don't waste your time and money trying or even thinking about it further.
It's not the fastest, but I've got a quick blaster with a decent amount of money in it. It is still in the dust compared to my LTR450. A 450 class machine is far superior in every way compared to a blaster. Low end power, top end power, suspension, rider feel, etc. far exceed the poor blaster. The blaster is a great quad, but these are in different categories. My girl usually rides it but I still hop on the blaster once in awhile and have a great time. Enjoy your ride for what it is.
There are always exceptions to anything with a nearly unlimited budget, but that's not going to happen for us mortals.
