Engine Break-in Period
Qualified Vengeance Motorcycles factory technicians prepare your motorcycle to be ridden upon delivery. Besides
initiating the critical engine break-in period, a check of proper systems operations has been performed and any observed
deficiencies corrected. However, to prolong the life of the engine and other components, it is required that you complete
the critical engine break-in period and follow the break-in guidelines below. These procedures are required to maintain
the factory warranty and improper break-in may void your Vengeance Motorcycles Limited Warranty.
CAUTION: SYNTHETIC MOTOR OIL SHOULD NOT BE USED IN YOUR ENGINE UNTIL AFTER THE BREAK-IN
PROCEDURE IS COMPLETE. DO NOT MIX PETROLEUM-BASED, MINERAL AND SYNTHETIC MOTOR OILS.
THE FIRST 50 MILES
The first 50 miles are the most critical for new rings and piston break-in. Most engine damage will initially occur during this period.
1. Keep the heat down by not exceeding 2500 RPM.
2. Vary the engine speed; do not operate the motorcycle at a constant speed for sustained periods.
3. Pay close attention to gearshift speeds, do not lug or over-rev the engine and never rev the engine in neutral gear.
CAUTION: LUGGING, OVER-REVVING OR OPERATING THE ENGINE AT HIGH RPM'S DURING THE BREAK-IN
PERIOD MAY RESULT IN DAMAGE TO THE PISTONS AND/OR OTHER ENGINE COMPONENTS. IF THE
ENGINE IS NOT PROPERLY BROKEN IN, YOUR WARRANTY WILL BECOME VOID. IT IS YOUR
RESPONSIBILITY TO CONTINUE TO BREAK IN YOUR ENGINE PROPERLY AFTER PURCHASE.
THE NEXT 500 MILES
For the next 500 miles, you must do the following to ensure proper break-in:
1. Do not exceed 3500 RPM or 50-55 mph during this period.
2. As above, continue to vary the speed, especially during long rides.
3. Pay close attention to gearshift speeds, do not lug or over-rev the engine and never rev the engine in neutral gear.
4. Avoid running the engine in 4
th
or 5
th
gear at very low rpm.
5. Avoid aggressive starts or racing from a stop with the engine throttle wide open.
6. Change the engine oil and filter at an authorized Vengeance Motorcycles Dealer or Service Center.
CAUTION: YOU MUST HAVE THE COMPLETE 500-MILE SERVICE PERFORMED AT AN AUTHORIZED
VENGEANCE MOTORCYCLE COMPANY SERVICE FACILITY TO CONTINUE YOUR WARRANTY IN FORCE.
FAILURE TO DO SO WILL VOID YOUR WARRANTY.
THE FIRST 1,000 MILES
For the balance of the first 1,000 miles, observe the following guidelines:
1. Continue to operate the engine at varying speeds making sure not to exceed 70 mph.
2. Vary the engine speeds.
3. Avoid engine overheating.
4. Keep speed at or below 65 mph.
5. Change engine oil and filter.
THE NEXT 1,000 MILES
When the break-in period is between 1,000-2,500 miles, continue to follow the same procedures as before.
1. The RPM range can be slightly higher than 3500 RPM or 50-55 mph, if needed.
2. Avoid over-revving and continue to observe the gear shift speeds.
3. Avoid overheating the engine or putting any hard strain on it (such as drag racing, trailer towing, etc.).
2,500 + MILES
After following the above procedures, when you reach the 2,500 mile mark, you have properly broken in your
motorcycle. Complete the 2,500 mile service at an authorized Vengeance Motorcycles Dealer or Service Center,
enjoy your motorcycle, have fun, and drive safely.
