      I have done Guwahati to my office, about 60 kms one way twice now. Road is a highway. I did constant stretches at 100 kph and for quite sometime. On open roads, with a good helmet, the bike feels beautiful between 100 and 110 kph. No stress. None!

        Answer in your question. You can ride as long as you physically can handle.
        Motorcycle engines are well made and can endure 24x7.

        For FZ25, I think the sweet spot is 90kmph.

          For God's sake, guys, its a frigging sportsbike! It's meant to be revved up till the redline! If you baby the bike buy riding it slow, there will be carbon deposits building up in your engine and one fine day, boom! Engine problems.

          The sweet spot for touring on any bike is dependant on the road and traffic conditions, and 80% of the bikes top speed. For the FZ25 that would be 120 kmph. Not 90. Honda Hornet and Unicorn can cruise at 90 all day under normal conditions.

            Rightly said. 120 on expressways is easy on fz25- control and stability wise.

              I did two 120 and 140 kms respectively trips this week. Bike has done just 1400kms and only first service. Still delivered 39-40 kmpl at 70-80 kmph. If your bike is past the running in, you can cruise at 100-110 all day long.

                What’s the source bud???
                Anything more than 40-50% of vehicle max rpm is bad for the engine. Unless your bike is something which has vvt or something similar.

                  My source is

                  1. an experienced tourer who has done more than 2 lakh kms on bikes.

                  2. My own experience. I've done 650, 730 kms rides with the throttle pinned at 120-140 kmph on the CBR250. The bike never overheated, nor got damaged.

                  3. My dad, who rode a splendor 650 kms at 50-70 kmph in one day.

                  4. Numerous bikers and bikes thread on Xbhp, which, if you have read, you wouldn't be saying the above. Latest one is in the Bajaj CT 100 thread. By Ashwin Prakash, iirc.


                  About your assertion on not crossing 50% of bikes rpm, please give me the source. Would be interesting reading. Because it's frigging hilarious, and any serious long distance biker would laugh on reading this.

                    As far as my experience of motorcycle touring since 12 years with honda unicorn, karizma and fz25, no harm to any of above engine ever occoured. I have done numerous high speed full day run.

                      Do you know that Engine oil temperature and RPM are directly related. Do you know that Oil thins at high temperature affecting lubrication, which is the sole purpose of oil to be in Oil chamber.

                      Do you know that High RPM, Engine head gets hot to the highest level. Piston and rings move inside this part. At such high RPM, do you think the rings wont get affected? Few bursts or at 70% of RPM range is Okay. But whole day at max RPM. You must be kidding.

                      Do you know that at high RPM, bike needs to produce more torque to stay at high speed, which means, fuel mixture should be rich. Burning Rich mixture is going to cause deposits on Piston and valves.

                      Do you know that Valves movement is directly related to Piston movement. If your RPM is too high, Shims take a huge hit, because of high temperature in Head at that RPM. Valves edges take a huge hit too.

                      Who said that if you ride at Max RPM, the engine will be damaged in one day. Its a long term affect, which damages crank, cam, rings and other parts. its not something which breaks in a day or so.

                      it really doesn't matter how many kms you rode. What matters is how pristine your ride was.

                      Probably i do not agree. Reasons mentioned above post.
                      Engine wont get damaged immediately. But shows signs of long term damage in short period.
                      Maybe i am more responsible. Responsible enough to ride a 1st Gen pulsar over 1 Lakh Kms without touching the engine.

                        Brother no one rides at constant high/top speed for long time. Constant speed is harmful to any engine.

                          Still my karizma engine never touched, even valve clearance never set after 60k kms which include 90% of touring. Not a big deal.

                            [MENTION=35081]kris123456[/MENTION] - arre sirji, you know, I know. And the guys who designed the engine know more than both of us. They have designed the bike to ride at speed. No one is talking about Max rpm riding. Calm down.

                              [MBS] Lubrication is not the sole purpose if oil. Oil is also used for heat reduction.

                              [MBS] for the Air cooled engines, head reaches at the highest point in the B2B traffic and not at high speed.

                              Do you know that at high RPM, bike needs to produce more torque to stay at high speed, which means, fuel mixture should be rich. Burning Rich mixture is going to cause deposits on Piston and valves.
                              [MBS] I disagree on this point. Due to rich mixture bike will bogs down or may loose power.
                              Do you know that Valves movement is directly related to Piston movement. If your RPM is too high, Shims take a huge hit, because of high temperature in Head at that RPM. Valves edges take a huge hit too.

                              I beg to differ on few of the points above. Please see my response above

                                Brothers, let me put this discussion to rest. Above all, riding persistently at high speeds is very dangerous. Forget the bike's engine, your own life is more valuable.
