Does Honda SP125 [2019-2024] have ABS or not?

Me too sometimes face this. It happens generally from third to second gear. But I think it's not a problem , I assume when you are not at a specific level that gear should be changed, it won't change. Slow a little bit extra & it will change. As you might have observed that you can ride 25kmph in 5th gear without any problem.

No, it is not mandatory to maintain any minimum fuel limit with the bike. Moreover, Honda SP 125 gets a fully-digital instrument cluster with real-time and average efficiency range.

It depends on you , i travel solo 180 km in uttarakhand= Kashipur — Ramnagar — Haldwani —Lal kuan— Rudrapur — Kashipur. i only take a small brake in Lal Kuan for about 20 minutes. although i ride continuously Non Stop. i also travel from this bike from = Kashipur -kala dhungi- Nainital ( take shortcut for Nanital from kala dhungi) it around 87 km the hills region. with a pillion. most of the time in hilly regions, i ride in second or third gear . it take some more power because of pillion, otherwise in solo ride to Nainital it runs smoothly like regular bike 100cc bike on mountain afterall its engine is 125cc ( this condition is only with pillion on mountain). after all it is good bike . The only cons i have see in it is the seat cushions, it make pain in long ride
