welcome to pakwheels brother (Y)
the three bikes cant be compared to each other due to the fact that JUNOON is 100cc...SPRINTER is 110cc...and 125...well its a 125cc :)...however i will try to briefly describe them
Honda CG 125:
one of the fastest bike in the local market with accelent accelration and top speed...however a typical carburettor doesnt help much with the fuel average..and 99% of the 125s i've ridden shake at speeds above 90...and u feel like the bike is gonna tear apart..
Suzuki Sprinter 110:
u gotta give it to the suzuki ppl that they made their mark with their SD-110s and SPRINTERS in the market where everyone said...MAIN TAY HONDA HI LAYSAAN :)...the suzuki sprinter is one of the best bike found in market today...exellent accelration...road grip...and stability at high speeds...outstanding fuel consumption due to BFI carburettor...some glitches with the speedometer which are xplained in other topics related to the bike...and the ROCK HARD SEAT :S
honestly i cant say much about the bike as i havent ridden it that much...but the times i was on that bike..it felt nice...intel gathered from owners said that the bike gives an mileage of 50+ which is definately not bad...good style and with economy places it above the counterpart HONDA CD-100 (Y)
