Yesterday at a Harley dealership I signed up for a "demo ride" and was offered the chance to ride any of several different 2024 model year Harley-Davidsons. I asked them to put me on a "cruiser" that was "one step up" from what I've owned before and currently: A 1998 H-D Sportster 883 and a 1996 Shadow 1100 c2.

They set me up with an FXLRs-- A "Low Rider" (naked cruiser, very low seat height) that had a 117 cubic inch engine. And not just the "normal" Milwaukee-Eight engine, but one that had a "Screamin' Eagle stage 2 power upgrade."




The bike weighed about 80 lbs. more than my Shadow ACE, but this lowrider felt lighter.
Would accelerate like a rocket !
This is the bike with the biggest engine I've ever ridden. Even counting that one time 30 years ago when my cousin, knowing I was experienced on a 250cc enduro type street-legal dirt bike and had my class M license, let me take his 1300 or 1400cc Suzuki bagger touring bike on a short ride in my neighborhood and up and down the medium-sized road in front of my subdivision.

But yesterday, about 10 of us took a 20-minute test ride as a group, each one on a different model of bike.

PS: 117 cubic inches is 1920cc.
Horsepower on the standard engine of that type is 107 HP,
with 126 foot-pounds of TORQUE.
I don't know how much that increases due to the Stage 2 power upgrade.

Goldwing F6B 1832cc 114hp 123ft/lb around 850lb bike

My 1000cc Versys is rated around 115hp, redline is at 10,000 RPM and bike weighs 574 lbs with the bags on. And that's the old man de-tuned 1000, The sportbike version is around 150 hp and bike weighs around 500 lbs. I should have gotten the 650 Versys...

My old Valkyrie has a claimed 100 horsepower and 98 ft/lbs of torque. Weighs close to 700lbs. It will go faster than I should ever go on a motorcycle.

I once rode a friend's CBX 1000. Scared the heck out of me. I think they have something like 105bhp.

Test rode an F6B Goldwing which was very fast.

Tested a Road King with the Milwaukee-Eight. Comfy, fast and it had an awesome custom paint job from the factory.

I was riding a Triumph Bonneville when a friend bought a 900 Kaw. Let me ride his one day. I had been considering giving up riding as that Bonnville was just plain scary, poor handling, poor ride, scary mechanical cable operated drum brakes, skinny tires,,,, Rode that Triumph to lunch about a week later and rode a new 76 KZ900 home, with the better power, handling and braking, figured I could ride a few more years...

A few years ago I had a near showroom condition '83 Honda Interceptor VF750F with the V45. Had 86hp. That thing was light and a serious rocket. I could have the front wheel off the ground in the first 3 gears.
I sold it to a collector that was missing that year in that condition.
At the time, I wanted a bike I could daily... and didn't realise until after I had it that due to it's age it was getting harder to find normal replacement parts for it.
So I sold it and bought my first Shadow 750, my 2007 Spirit (shaft) that I did cross-country rides with it (mainly to Sturgis and back)... that's when I fell in love with the Shadow and have had them ever since.

Drove a friend's 73 Vette with a 510 ci big block after tuning his 800 (850?) double pumper Holley carb for him. All new suspension with urethane bushings, hi Performance auto trans. fresh paint, Gobs of power and precise handling,,, Almost made me buy a Chevrolet. I still look at Vettes. The right one hasn't came along yet.

For fast bikes I owned a 2001 Suzuki Hayabusa. It's 1299cc engine was rated somewhere around 170 hp. With it weighing in around 550 lbs, it was a real rocket ship.
After that I rode a 1000 GSXR for a number of years. It's inline 4 put around 190 something bhp. with the bike weighing about 100 lbs less than the Busa, it was a bit of a challenge keeping the front tire on the road.
My current bike, the 21 Street Bob has the 114 in it with the Stage 2 Screamin' Eagle package. Obviously, a bunch heavier than either of the two Suzuki's and nowhere near the bhp, but the throttle response and overall fun ride can't be beat. Definitely a different kind of ride.
I'm thinkin you enjoyed that demo ride?
I liked the ergonomics of that Low Rider but my Stret Bob has 11" risers and pull back Buckhorns coupled with the Saddleman seat so I have a bit more layed back riding position vice that slightly aggressive riding position on the Low Rider.
 
#14 ·
So they say the 114 is putting out in the area of 82 hp with around 115 lbs torque. The stage 1 Screamin' Eagle is supposed to add about 10% on top of that and then depending on the cam, another 5-10% with the stage 2.
The biggest thing I'm having to get used to are the ABS brakes. Still having a hard time wrapping my brain around the idea of squeezing that right brake lever hard.

200 HP is insane!
What about the old days when 20 HP would get you around and have a fun ride?
My 1963 Honda 305 Dream was 24 HP, and ran down the freeway with a buddy or my girlfriend on the back.
Why does anyone need to go 200 MPH?
Unless on a race track?

The subject matter is what not why. Stay on point here. :giggle: I see here everyday about slow bike stories. It's refreshing to see others power cravings over the years. Keep the bench racing going.

BTW Swifty, my 91 ci. Fat Gurl @ 800 lbs. can lift the front wheel under hard accel in 1st. gear very much like a 1st. gen V4 Sabre. Friggin cool! And no I don't do burnouts. :giggle: And no 1600 Kawasaki Vulcans are the epitome of "slow bikes".
I'd say a chain driven VT 750 is quicker.

Lil' Sista was one of a couple Honda's every young lads desire in 70'. The most popular, the CL350 Scrambler which was my favorite next to the XL250.

,,,which has less than 2/3 of the power of the sportbike 1000 version of that engine, which is rated 200 hp and a redline of 13000. The powerband is in a lower rpm range on the Versys. I'd call it a more manageable power. Also a lot more comfortable than the sportbike. (Corbin seat/better windshield a must.) I noted I should have gotten the 650 twin Versys. Sales person said I'd need the 1000 for 2-up. Never believe salesmen... (Though I did know better from taking trips on my 750 ACE...) Hard to believe I've had it for 5 years now. Average mpg since last June is 47.2.
My thinking is if it can take the ninja power, this engine ought to be bulletproof in Versys trim.

Funny this thread would crop up now. We were visiting my wife's uncle yesterday, and someone stopped by to pick up his first ever bike that he had just purchased, a Yamaha R6 that the uncle was tuning up. When I showed him pictures of my bikes, his first question was, "How fast will they go?"
After showing him how to do up the chin strap on his $600 Sonic the Hedgehog helmet ("It was the most expensive one they had."), he wobbled down the driveway and onto the road, paused (not stopping) and pulled out. While listening to him scream down the road (missing shifts all over), I turned to my wife and said, "Remind me not to ride with him. He's going to kill himself on that thing, and I don't want him to take me out when he does."
I guess my point here is that although lots of power isn't necessarily good or bad (I've had my share of high performance street rods), if you don't know what you're doing, things could end badly.

Not sure, but I suspect that poor kid would find a way to kill himself on a CT90.

But yeah, it's a real problem; I guess people do this a lot. Straight out of BRC (if any training at all) and buy the biggest bike they can get their hands on. Part of the reason I ended up with a 750 was all the cautions online against starting out on a "litre bike". I didn't realize until after the fact, that sport bikes are a tad different from cruisers in that department. :ROFLMAO:

Yeah maybe a lot of HP is OK for fun, if you can control it safely.
But rider skill and brakes are be important even with low HP.
See the video.

I think still the fastest vehicle I have had the pleasure of driving was my Kawasaki 250 two stroke bike with track gearing. I seemed you hit that power band and blinked you were doing 70. I miss that bike, wish I woulda saw through the hard times I was in and kept it. Can't even buy it back in Cali anymore. Loved the two stroke power band.

That's my main gripe against the R1200. I've did many thousands of miles on one on the open road and loved every minute of it. Never cared to commute on one though. That's been the big difference with my Street Bob. Goes down the highway like silk yet easily maneuverable in town and an enjoyable commute.

I come from a time when a fast Norton Commando made 58hp at the crank and the game changing CB750 made the same and the 60hp Kawasaki 500 triple was suicidal.
I have ridden a 140 hp liter Kawasaki race bike around the block and a few claimed 100hp Harleys for some miles, but that is not my thing one way or another.
My 750 ACE was too slow for me though and I fixed that, although that was trade off, it's now a comfy chair that can get out of it's own way.
My Versys 650 seems about right for me these days, plenty of power for my road use, decent handling and enough versatility to handle speed bumps and pot holes while gathering forgotten groceries.
