Where did you get the measurements of the piston and cylinder? A 98mm piston will not fit in a 96mm bore. Where did you get a 98mm piston? If you are new to this, order a piston from a reputable source (RMATV, Dealer) for your particular model. The standard bore and stroke for your model is 96mm x 62.1mm.

I searched the specs for the bike that I have on Google just typed the exact model and year and I found the measurement for the bore but the piston I found it on a website in the country I live in its called motologistika and thank God I didn't buy the piston I would have wasted my money for nothing I thought let me ask someone first.

I looked at the website for a 2015 piston and the one that comes up is the ProX 01.4406.B, if that's the one you are looking at it measures 95.98mm so that would be a standard size piston for your bike.  Below is the link.
