Q. Why is the gear shift problem in SP 125 ?

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.

Huge gear problem: 1) Often you will not reach Neutral from 2nd or 1st gear at the first attempt 2) While changing gear you may stuck between two gears 3) Gear become hard and do not freely shift if you are not at the right speed

I brought new sp 125 2023 I am facing some problem regarding gear shifting. Bike sometimes did not get 8nto first gear from neutral and something it's gear change it from 2nd gear into neutral without staying at 1st. And another bike did not neutral from first gear.
