The Low Rider ST was released in 2022 and it no doubt made a big wave. Outside of the touring models, mainly the Street Glide and Road Glide, the Low Rider ST is easily the most popular model. For good reason, its built on the Softail chassis which is quick and nimble, awesome 117ci M8 power, inverted forks for excellent handling, and the list goes on. I had my eye on this bike since its release but couldn’t get past the stupid digital gauge and the smaller bag on the right side. Yes up until 2025 the bike featured a 2 into 2 exhaust resulting in the right bag needing to be smaller to fit above the exhaust. For 2025 they went with a 2 in 1 exhaust allowing the right side bag to fit above the exhaust and be the same size as the left side bag. The digital gauge was just not Harley if that makes sense. I would expect an analog gauge with a small digital screen like they have done on previous models. Well in 2025 they switch to an analog speedo with small digital screen for basic features like trip A/B, Clock, RPM, etc. Also for 2025 they finally outfitted the bike with all LED lighting. This is just a must at this point as it increases safety and service life, no brainer. Let’s dive into the bike!

The new instrument cluster is beautiful. I really like the analog speedo and digital screen combo. Just below the gas gauge you will see one of three symbols for your ride mode, yes for 2025 we also got ride modes! Now I will say I could care less about stupid ride modes. My ride modes are my hands and feet. I am in complete control I don’t need a nanny numbing or increasing throttle inputs, I got it under control thanks. But this is a positive to newer riders! Newer riders can lean on some assistance while they grow and develop your skillsets. Part of that electronics boost is also traction control and abs, both of which are lean sensitive. Again don’t need it but I do appreciate these two systems and they work extremely well. Sometimes sh*t just happens and having ABS/TC there to cover you in the event of an emergency braking maneuver is money! Check out the new instrument cluster below!

Street Mode - I keep the bike here 99% of the time. I find that it gives the bike the most natural feel. If I do go out on one of my long twisty rides where I am not really starting from a stop ever I will flick it in Sport Mode just to mess with it but always end up flipping it back.

Sport Mode - Basically makes all inputs amplified. I absolutely hate this setting for starting from a stop. You can move the throttle 1mm and it fly to 3k rpm, which isn’t how it would work if it was cable driven. This makes having an intimate relationship with the friction zone very difficult compared to street mode. So if you’re like me and you like having more control for ripping tight u turns and just more control over all, skip it.

Rain Mode - Is the opposite of Sport mode by numbing all inputs. I can see the value here as on slick roads having number input would help prevent wheel spin. To me that is a training failure not a bike failure. You need to learn how to work that friction zone to smoothly apply power to the rear wheel and not rely on some electronic nanny to save you from your lack of skill. Get training and practice.

New for 2025 is the all LED lighting. When it launched in 2022 it had a LED headlight but brake and turn signals were still all incandescent. Everybody has seen a million bullet style turn signals from Harley and that’s what you get here. I think the star of the upgrade is the rear tail light. Its a beautiful piece that flows with the bike and is a major step up from the previous unit.

New color for 2025 that was also available in Street / Road Glide…. Iron Horse Metallic is stunning. One thing I always tell people when they bark about the price of a Harley Davidson is to look at the paint quality and options. They always have super stunning color options and the quality is top notch. Once I saw this color I knew it was the way to go when purchasing my Low Rider ST. Iron horse Metallic is a gray bluish base tone with gold, purple & green flake. The photo below was shot with polarizer so I could cut the wavelength of the glare so you could see the flake!

Then when shot outside of direct sunlight is has this dark gray / dark blue tone. Again it’s just beautiful and I can’t say enough positive things about it.

Let’s talk about the absolute beast of a motor they put in this bike. 117ci High Output Milwaukee 8! Not only is this a lot of displacement for a middleweight bike, the HO gets some special treatment over the other variants of the 117 M8. I think most notable is the Stage 2 Screamin Eagle Cam straight from the factory. Essentially this is a CVO Road Glide 117 in a middle weight bike. With this cam package it moves the torque up to 4,000 rpm this also moves peak HP to 5,000 rpm. What does that mean? It means this bike likes to be revved out and you can really feel the power start to come on at 3,000 rpm and up! Now I do have full exhaust so I did add the Screamin Eagle module and uploaded the tune for my mods and bike. The result is VERY noticeable, and I was shocked it was that much of a difference. This is not some placebo effect. I had the tune loaded and then had to pull the main fuse to perform some other work. I had the main fuse pulled for a few hours and on the test ride I was like what the heck this thing is missing all the punch! Came back to the garage and opened the app to see it had no tune installed. Reinstalled said tune and went back on the road and boom it had that explosive power north of 3,000 rpm! I do plan to do the custom tuning option in the app and will report back about my thoughts. As usual the motor is a work of art and Harley Davidson did a great job hiding wires and what not.

In the first image you’ll see I swapped breathers. I do love the look of the Heavy Breather that it comes with but for me my knee hits the elbow of the breather. I swapped it out for a Feuling Breather and problem solved. I absolutely love the look of it and the polycarbonate element that allows you to see the velocity stack and throttle body is just awesome! Note I did swap my velocity stack for the optional Red Anodized part. The factory one is polished aluminum and looks awesome but wanted to do something a little different.

I think the first thing anyone does to their new Harley Davidson is swap the stock exhaust out. It’s a pure crime that they roll off the showroom floor chocked up like that. I took me a while to find my exact bike so I had already researched different exhaust systems. By the time I landed the bike I already knew what system I wanted. I went with SP Concepts Big Bore with Works Header. The sound is absolutely perfect to me. It’s super deep and not obnoxiously loud. When cruising at 75 miles an hour it's barely noticeable, but when you rip the throttle it lets everyone know you’re there! The welds are perfect and the works header is a PIECE OF ART. It is worth the up charge and additional wait time for the works header. When I ordered mine straight from SP Concepts they quoted me a week and they were dead on the mark. I have seen the wait time several weeks and up to a month. Keep in mind places like TC Bros stocks these pipes so you may be able to find one in stock from them. It is worth the wait regardless.

I don’t care what bike you buy, you’re gonna have to do some fine tuning of the bikes ergos to be setup for you. I found the seat too low and too far back from the bars. The foot controls are just pegs and the brake lever & shifter aren’t adjustable. Bars were too low and too far forward. Also the bike has zero crash protection. So let’s dive into that.

First up are foot controls. I swapped out the stock pegs and levers for Thrashing Supply Aggressor mini floorboards. This larger foot print is much more comfortable for any type of riding. Adding their billet brake lever and shifter with adjustable linkages not only has killer looks but allows you to fine tune their position. They come in different styles if the aggressive style isn’t for you.

Next is the seat. The stock seat left a lot to be desired for my height and inseam. The Saddlemen Tuck N Roll is super comfy and raises me up and forward. Plus it looks beautiful and really compliments the lines of the bike.

Lastly we tackle bar position and crash protection. Bung King offers one piece handlebar risers that use the factory upper clamp. This makes the swap super easy, I went with 6” risers with 1” pullback, this allows me to use all factory wiring and cables. This setup got the bars back to me where I wasn’t stretched forward. Bung King also offers highway peg crashbars. These look rad and offer protection if the bike goes down. I also find I can rest my feet on them for a stretched out position on the longer rides. To match that I used their Passenger Peg / Frame Slider, two birds one stone. Passenger foot pegs with added crash protection if you have the bags on and the bike goes down.

Classic Harley Davidson high detail. They could have just left the fork tops plain like everyone else does but they took it a step further and added some beautiful detail.

This is my 5th Harley Davidson with the first being a new 2006 Street Glide. I have to say if you’re looking for a bike that does it all from crushing corners or crushing miles, this is the bike. It’s powerful and comfortable with all the classic Harley Davidson styling and high build quality you could ask for. LETS RIDE!!!
