Breaking in the Triumph Street Triple Enginewritten by -- February 12th, 2008Filed under: 2008 Triumph Street Triple,Staff Bikes | Comments (0) |

These engines are one of the more difficult motors to break-in, and there’s an ongoing debate of whether to do an easy or hard break-in. There has been no long-term comparison of the two processes. So, I’ll tell you what Triumph recommends and what I’ll end up doing.
In the Triumph Street Triple owner’s manual, the break-in process for the first 500 miles is as follows:
-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
Now, here’s what I’m doing, as advised by the mechanic at our local Triumph dealership. For the first 100 miles, I was very gentle with the bike. I didn’t do any hard accelerating or braking. I didn’t load the motor at all (I was in the process of learning to ride so I wouldn’t have done this anyway).
Since I have passed 100 miles on the odometer, I need to gradually increase the range of revolutions. Right now, I am going as high as 7000 RPMs. I’ll eventually need to increase the RPMs to 11 or 12,000 RPMs. I need to put a load on the engine and do a lot of hard accelerating and stopping. I also need to do a lot of engine braking. All this means is that I’m riding at a gear lower than what I normally would be at. I need to continue this process until the first 600 mile service.
Street Triple engines come lubricated with a semi-synthetic oil to help with the break-in process. If the engine is not fully broken-in, full synthetic oil is not recommended for the engine during the first service.
Stay tuned for more tips I pick up!
