    Hello guys, I had a close call today. I was just starting to move from stoplight in 1st and then shift up to 2nd gear doing roughly 15-20 kms/h and then the engine suddenly died and the rear wheel locks up, I started skidding nearly dropping my bike. I'm not sure if I did anything wrong while driving slowly in low rpm on 2nd gear or if it was a mild engine seizure.
    After the the stall/lockup I restarted the bike and all was fine again, rode it with no problem, apart from the the obvious black doom of what happened in the back of my mind, making me feel a bit less confident.
    What could be the reason? Is something wrong with my bike or operator error?
    I had a similar experience last week and I posted about it a couple of posts ago, but I'm my case it appeared to be a complete electrical shutdown during acceleration in 3rd gear from a start at a signal, almost exact same situation as you.

    I'm pretty sure it's not a loose battery connection issue but will definitely get it looked at during the 1st service.

    Not quite sure if the rear wheels locked up, but could be possible if the engine just dies then naturally there is no drive going to the rear wheel. Looks like it's the same case as mine. Did your instrument cluster display also shut off?

      No, the instrument cluster display is fine, it's all lit up. I'm sure the battery's working fine. The weird thing is the engine just shut off and the rear wheel locks up and skid nearly throwing me off.

        Me 2 faced the same issue..but after first service it never happened.

          Then I'd guess it's an ECU issue? Can't really understand what else would cause it.. sparkplug problems could I guess.. But they don't show up until a few years of use

            Any performance modifications that can be done to FZ25, mainly to increase the top speed, like sprocket change?

              Don't know much with Fz25 but it happens with me few times. I have a P150 and it generally happens when i am not at correct gear (happens in gear less than 3rd) and RPM usually at lower RPM range and the engine just stalls. I have been pretty cautious about it and pull the clutch instantaneously just to avoid real wheel lock but sometimes i do miss out on it. Never bothered much since i usually keep engine RPM above 2-3 all times.

                Faced similar issue last week.. While turing my bike. Unfortunately fell down and left side RVM cracked. 😥

                  Engine stall would occur in any bike. Have faced this on R15, Bajaj Avenger, Hero Xtreme, etc. The problem is due to riding at low speeds at higher gears, or upshifting at lower rpms. FZ25 is a 250cc machine with longer gear ratios. So, you have to reach a min rpm before upshifting. It's just about time you get used to upshift at correct rpm. Again every bike is different and has its min rpm to upshift. Someone, here had mentioned 4000 rpm. Not sure about that though.

                    If reaching a minimum rpm before upshifting is the problem, I've had my fz25 for 4 months and I usually shift around 3000-4000 rpm and never before had I experience this kind of engine stalling and rear wheel lock.

                      Yes, when engine stall occurs, it just stops the drive from revving freely, causing the drive to lock up the rear wheel. Be careful with this one, because at times it can be extremely dangerous. Once, I was almost rear ended by a car on a highway. Using the clutch lever would help to free up the drive. But, using correct gear at correct rpm is the key. Low speed at high gears or upshifting at low rpms are the reasons for engine stall.

                      Its not about how much time one has used the vehicle. But, the rpm at that very moment. I have 17 yrs experience in riding two wheelers, still I face this problem at times :-D. Don't worry, your bike is perfectly fine Again, if you are facing problem while you start at first gear, then its the idle rpm. You need to adjust the idle rpm to the recommended rpm in the manual. At times, service guys lower the idle rpm down for better mileage.

                        Thanks for the input Mate, but to be more precise about my situation, It happened while I was in 2nd gear doing rougly 3000-3500 rpm. And the idle rpm is around 1300-1600 rpm.

                          Then, its definitely because of low rpm. Idle rpm seems right. Try it out again in a safe place. But, be careful on busy roads. Like I said, you might get rear ended by vehicle behind you. Use the clutch to veer away to safety.

                            Hi, what was the fuel level like? I experienced a similar issue during a test ride , that bike was too low on fuel and when I sensed the engine failing I simply gave more throttle and it was ok. So I assumed it because of the low fuel.

                              Ben riding since 2003.. so definitely want my riding that caused it. The bike died on me - including electricals when I was accelerating between 2nd to 3rd so for sure there's no chance in hell the rpm was off for the great selected

                                The tanky was half full. I guess it's not because of the fuel level.
