Run-in A New Twin-engine

[ThomasG]

Hi Folks,
waiting on my brand new Street Twin, sheduled for October, I wonder how to best ride-in the engine.
How would you do that to minimize wear and tear and optimize engine performance for the long run?

If it's a brand new bike I would just follow the instructions in the owners manual.

I varied gear, RPM and speed for the first 100 miles. Now I just avoid full throttle until 500 miles. The book says:
During the first 500 miles (800 km):

• Do not use full throttle;
• Avoid high engine speeds at all times;
• Avoid riding at one constant engine speed, whether fast or slow, for a long period of time;
• Avoid aggressive starts, stops, and rapid accelerations, except in an emergency;
• Do not ride at speeds greater than 3/4 of maximum speed.

General Information
From 500 to 1,000miles (800 to 1,500 km):
• Engine speed can gradually be increased to the rev limit for short periods.
Both during and after running‐in has been completed:
• Do not overrev the engine when cold;
• Do not let the engine labour. Always downshift before the engine begins to 'struggle';
• Do not ride with engine speeds unnecessarily high. Changing up a gear helps reduce fuel consumption, reduces noise and helps to protect the environment.

Hi Vector,
thanks for your answer.
Looks like the usual run-in for all types of engines, nothing special.
I'm always afraid of being too careful with running-in and as a result not have maximum engine perfomance afterwards.
Maybe a stupid thought, lol.
