rieju mr300 vs 17 ktm, are the counter balance engines worth the extra money

[abraham]

i want to buy a 2 stroke for comuteing and travelling.
i have an old mz301 and a ktm 450.
for the price the rieju looks like a fantastic deal in my country.
but since i'm doing a lot of road miles, i want to ad that comfort of the counter balance, if it noticable.
i have experience with dirt bikes on roads, 50/50 tires and rim balancing +steering dumper, works for me preety well.
then i'll look for 17-18 carb exc 300.

thanks a lot
