Why does the 250r have the front brake...

corksil · January 18th, 2016, 10:13 PM

On the right hand side of the bike? Has anyone noticed that almost every single bike has the front brake caliper/rotor on the left side of the bike, same as the clutch -- and opposite from the exhaust pipe.

Seems logical that bikes place the front brake on the left fork to counteract the extra weight of the exhaust on the right side.

Yet the 250r has both exhaust and front brake on the same side.

There must be a reason.....

Anyone?

I assume manufacturing costs. A shorter brake line means saving a few cents.

Long time ago my friend working for a big German car manufacturer found out that the main wiring harness of a car-series could be a little bit shorter by some mm and for that they'd pay him a bonus of 400,000 Deutsche Mark - good times that have been...

For whatever it's worth, the Gen1 EX500 has the rotor/caliper on the left side. They moved it to the right side for Gen2.

Like the others said, I assume it's cheaper and less complicated to simply keep the caliper/rotor on the same side as the lever.

It could be on the right because on the pregen, it had dual exhaust. So logically, it didn't matter. Then they simply left it that way because their machines were set up that way.

Also, the brakes and exhaust are not the only things that are off center...

There's wayyyyyy too much going into this to pinpoint it easily.

Maybe their manufacturing process/tooling is easier to have them on the right side. Maybe every other single rotor sport bike has them on the right side and they want to look like the cool kids. Maybe the right side calipers are easier/cheaper to make. Maybe there's something weird to the forces and it's easier to put it there. Maybe the lead design supervisor liked it better on the right side.

And just to throw a wrench in the logic... there exists a rare unicorn pregen model that has dual front rotors from the factory, so we know they had the manufacturing/assembly tooling to make both sides...

Bottom line: who cares? it still stops either way.

Good said Chris.
As German let me bring another point into the discussion to look at.
Maybe you all know (or maybe not) in Germany there is a big thinking about safety (TÜV is known?).
So another reason could be to keep the 'hot part' away from pedestrians - I guess you know in Japan the traffic is left-sided, so the brake is directed to the street-side.
But what do I know?

Gyroscopic pressesion makes the wheel want to turn left. Perhaps mounting the caliper and disc on the right counters this?

Yeah what he said

Things like shorter easier brake line routing as already mentioned here.

Also rear brake is on the right, so why not make it consistent and put front also on right.
