I had an LS125R - the other sporty two stroke made by Honda Thailand and that would indicate 100mph on the redline in 6th. Honda's figures claimed 24 horsepower @ 8500rpm at the crank for that bike.
CBR250RRs give 45 horsepower at the crank and allegedly can do 115mph.
Going purely on comparisons with other machines based on how much power they make and what top speed that allows them to do, i wouldn't think your bike could do a genuine 125mph.
Before I got my 28SE I had a '92 CBR250RR, which made 45HP on the dyno, and given a long enough bit of road got close to 200 kmph.
Maybe if you had a downhill runway you could get the 150 to 200
