Does the 2003 Honda Shadow VT750DC have a rev-limiter?

I had to pin the throttle to the wood to avoid an accident and at the top of first, it sounded like I hit a rev-limiter. Does this bike have a rev-limiter or could that sound have been something else?

It should have one, reach it and the bike will sputter and no higher RPM's.You can try it and tell in any lower gear.

Yes, your bike has a rev-limiter.

It certainly sounded like one, but I didn't think that a low-tech 14 year old cruiser would have one. I wonder how it works? I know my Ninja's rev-limiter is computer controlled, but didn't think an old Shadow would have this type of technology.

My 82 Seca 400 had one.

It's not like a spark limiter is really that advanced. MSD has been making "Rev Limiters" for 50+ years. You simply limit the rate of the spark from the CDI module. This can be done by computer, or by design. For Honda, making a CDI specific to a given engine allows them to simply build a CDI that only sparks "that fast."



There's no such thing as "Spare Time" or "Free Time" or "Down Time."
Time is time. All you have is "Life Time." GO.

I did some research on rev-limiters and even before the ECU days there were crude rev-limiters. Even the 1950's VW Bus had a rudimentary rev-limiter. I would have never guessed that.

That's funny about the 1950's VW buses with rev limiters. The old buses had a reduction gear set up on the rear axles so the engine turned pretty fast when you tried to go 60 MPH on the freeway. So a limiter would be smart.
A friend of mine back in the late 1960's had one of the old buses and the family headed back east from Southern California through the desert. He let his wife drive for part of the way and he fell asleep. He said it sounded awfully noisy back in the rear of the bus where he was sleeping.
Bad thing is that she was driving in 3rd gear instead of 4th and fried the engine.
The old air cooled engines where hard to keep cool even in the proper gear.

Only a biker knows why a dog sticks his head out of a car window.

There is a previous post from 2010. All engines regardless of motorcycle or car have a built-in rev limiter. It's called valve float. Once you achieve a certain RPM the valves lose efficiency. Therefore it limits the ability go any faster in that particular gear. Look on YouTube for pictures of engine design and check-out valve float.
