Kawasaki Klx125l vs Suzuki rm85l?

i got a 03 rm85l stock but geared down for more low end. it can catch up with my kx250 when it hits the power band. looking at this klx125l with a fmf powercore exhaust and i might like to trade with my rm85l and was wondering how much power in comparing with my rm85l. want to get something new and would like to mess around with a 4 stroke for once. my rm85l has absolute no low end power and i do a lot of trail riding and hill climbing so low end is a must but i ride at the track sometimes. so the question is power, track capabilities and small jump capabilities.
