Re: Yamaha FZ 25 Owners Reviews and Experiences
Sirji, Biggest Designer is God. God gave us legs, using which we can run at more than 20 KMPh. Try running for half hour. But You cant do it.
Try walking at 6 KMPh for 6 hours. You can do it.
Companies make products to be reliable to a certain extent. All companies depend on returning customers. All companies have high percentage of Returning customers and less percentage of new customers. They want to keep the old customers to come back.
Heat is the output. If the oil lubricates, it gets crushed between parts, which transfers heat to oil. if you are rotating at 12000 RPM, Are you allowing oil to get into parts and lubricate and transfer heat? Why Race bikes on track use 0 w 20/30/40 oil? They want oil to be like water to keep Lubricating the engine and they dont care about its reliability. It should run for that race. That's it. Do we use such low viscocity oils? why don't we use? because, consumer products are meant for longevity and also not revved like Race bikes.
Riding at max RPM is not bad. But continuously maintaining that RPM on highways.. is bad in my books.
Agreed. Head reaches max temperature in B2B traffic, but that wouldnt cause much damage. Because Engine RPM would hardly be 1K or 1.5K. The amount of friction generated by Rings is less. But at high speed, even though head temperature is less, the RPM is 10 times more. When a component moves that fast, it does some damage.
At high RPM, engine doesn't bog down. The valves movement and pistons movement are so fast, the pressure of the piston is so high that The air fuel mixture gets compressed and combustion happens. Combustion effectiveness is questionable, depending on the bike. Unburned fuel gets ejected into exit chamber. and some remains get transferred to piston as junk.
Some people said, even they rode their bikes at max RPM but they are running fine.
The damage can only be assessed when the engine is opened. Also, valves quality should also be considered.
Just check any bike's Torque and power charts. Where they meet, thats the max point. Anything above it is just for fun.
