Engine Operating RPM Range

Postby jtspel » Fri Apr 24, 2015 9:30 pm



HEllo folks,
Just purchased a New(to me) 05 gl1800 with a new MotorTrike Razor kit. This is my first GW and I am really enjoying it...so far.
I have ridden Metrics and Hardly Davidsons...but the GW is a much different Bike for sure.
My question is: what is the best RPM to maintain without lugging the engine in 5th
gear?

Here's what the manual recommends:

Recommended Shift Points

Ride in the highest gear that lets the engine run and accelerate smoothly. This will give you good fuel economy and effective emissions control. When changing gears under normal conditions, use these recommended shift points:

Shifting up:
From 1st to 2nd: 12 mph (20 km/h)
From 2nd to 3rd: 19 mph (30 km/h)
From 3th to 4th: 25 mph (40 km/h)
From 4th to 5th: 31 mph (50 km/h)

Shifting down:
From 5th to 4th: 22 mph (35 km/h)
From 4th to 3rd: 16 mph (25 km/h)

To avoid lugging the engine, you should run in whichever gear keeps your tac above 1000 to 1200 RPM. In fifth, at 60 MPH you should be at around 1850 or so. The foregoing though is for a two wheeled bike. Probably not quite the same for a trike, but it will be close. The RPM to avoid lugging should be the same.

I blew this one... do not know where my memory went. In fifth, at 60 MPH the RPMs should actually be around 2700.
