Don’t Settle for Less Than the Best
When you’re taking on rough terrain, you need maximum control—sloppy steering from a worn out rack and pinion just won’t cut it. Every rack and pinion breaks down eventually, right? No way! Don’t settle for anything less than the best. Get SuperATV’s Polaris RZR 900 RackBoss 2.0 Rack and Pinion. We built it to never wear out with our X24 technology. We use a unique dual-bushing design that reduces wear by more than 50%. A RackBoss 2.0 rack and pinion lets you add big tires, lifts, and lots of weight without ruining your steering. It may not be the most flashy upgrade, but you’ll notice it every time you’re behind the wheel.
Dual-Bushing Design for Strength
X24 tech is the answer to the wear and tear that destroys most rack and pinions. To make RackBoss 2.0 the best rack and pinion, we use durable PTFE bushings at both ends that eliminate play from the internal gears and tension spring. Altogether, X24 tech reduces wear by over 50%. We also include a built-in grease fitting so you can keep everything well lubricated. Better lubrication + X24 tech = an unkillable rack and pinion.
Solid Steel Bar Z-Bend Tie Rods
Our heavy-duty tie rods are built to take a beating. They’re made from a full 1” diameter solid steel bar. The heim joints are pretty hardcore too, with 16 mm rack threads and 3/4” rod threads. These tie rods are also built with a special Z-bend design that’s stronger and more reliable. The bends are reinforced with custom gussets for superior durability and performance. With tie rods like these, you’ll be able to take on the roughest trails without hesitation.

Rich Espresso, Great Value
Color: A-Brushed Silver
I’ve been using this espresso machine for a little while now and honestly I’m very happy with it. I wanted something simple, affordable, and easy to use without spending hundreds of dollars on a fancy coffee maker, and this one does exactly what I need.
The espresso comes out rich with a nice crema and the milk frothier works really well for lattes and cappuccinos. It heats up fast and doesn’t take much effort in the morning, which I love.
One of my favorite things is how easy it is to clean and maintain. The removable water tank helps a lot and overall it doesn’t feel like a machine that requires constant work.
For the price, the quality is surprisingly good. It looks nice on the counter, feels sturdy, and makes coffee that tastes much better than I expected

Very good
Color: A-Brushed Silver
Here its my review for this espresso machine. The stainless steel design looks modern and premium, and it fits perfectly in small spaces without taking up too much room.
The espresso comes out with a rich flavor, and the milk frother works great for making lattes and cappuccinos at home. I also like the pressure gauge because it helps monitor the extraction process.
Perfect option if you want café-style drinks without spending a fortune on a large machine.
Easy to use, easy to clean, and looks beautiful on the counter.

This coffee machine exceeded my expectations in every way. The stainless steel construction makes it sturdy and durable. It heats up quickly, brewing coffee at the perfect temperature for a smooth and balanced taste. I love that it runs quietly and doesn't take up much space. The water tank is easy to refill, and the filtration system is highly efficient. Cleaning is also simple, which is very important to me. It's an excellent choice for both coffee beginners and experienced coffee lovers.

Actual espresso! Great as a backup or for vacation home or hotel room.
Color: Anti-Fingerprint Silver
I'm an experienced (20+ years) home barista. But my Italian "prosumer" machine (Andreja Premium) is in the shop for new gaskets & gauges, and I have no real backup. Nespresso is easy to use but not true espresso--looks good but not espresso flavor; adequate with Aeroccino to make fake cappuccino. Tried the "inverted Aeropress" hack. Nope--strong black coffee but still not espresso. My old camping Handpresso+Illy pod? My arms ache from pumping and barely any crema till end of brew--spewed all over the sink.
This java junkie needs her 'spro! Found myself standing in Target staring at a Breville Bambino...for $200? $50 steam toys? Been there, done that. Saw this surfing Amazon, and thought "for just one Benjamin, why not?"
Arrived overnight. Surprisingly sturdy, easy setup. Not used to tiny (51mm) portafilter (which the manual calls a "funnel" and is taller than my pro 58mm portafilters) but I also have a good wood&steel tamper I bought for my first Krups pump machine 40 yrs ago. (The plastic one with the scoop at the end in the box makes a great cat toy). Filled it, did a cleansing steam wand "purge" per the easy to follow instructions on a sticker on the side of the machine. Ground some Metropolis "Red Line Blend" espresso beans. First try "choked" the machine so I ground a bit coarser. Hit the button and...OMG! Real espresso! Flowed out in rusty brown "monkey tails!" Medium brown crema! Piping hot! Tasted it and OMFG! It's the real thing!
Noisy, but so are all true vibe-pump espresso machines. Only reason to remove a star was that the puck is wet and takes several slams against the bar of my knockbox to dislodge the grounds. The espresso it makes is nearly as good as what came out of my Andreja Premium (which demands careful dialing-in, WDT stirring, leveling and calibrated tamping). Certainly better than what Starbucks serves (much less the superautomatic machines in gas station convenience stores). Haven't tried the steam wand yet, but I bet it'll make finer pourable microfoam than the stiff stuff from my Aeroccino. Maybe not latte art quality, so what? But the espresso is good enough that you'll likely want to drink it straight.
TIPS:
1. RTFM ("Read the Friendly Manual")! Keep the nice illustrated quick-start card close by.
2. Use the 2, not the 1-cup basket. Unless you're an absolute newbie, don't rely on the automatic "1-2 cup" button; rather, use the power switch (has a little "hand" icon signifying "manual") to start and stop the extraction before "blonding" (pale crema) occurs.
3. Don't grind as finely as you would for a prosumer machine, especially not a heat exchanger with an e61 grouphead. You might find that the cheaper burr grinder you use for drip or press, on its second-or-third-click-from-finest setting, works better than a commercial grinder. (Mine's a 2-yr-pld Baratza Encore, not even advertised as for espresso). A pricy hand grinder is overkill.
4. Don't tamp as hard as you would for a prosumer machine either. In a pinch, the plastic "cat toy" in the box is fine.
5. Run a couple oz. of water, w/o the portafilter in place, after you brew your shot and knock out the puck; then wipe the group screen dry.
6. To turn the machine off, press the power/manual-brew button for at least 2 seconds till the light turns off (otherwise you'll be releasing water through the group screen).
7. Use fresh beans less than 3 wks old (preferably 7-10 days post-roast date). Grind for each shot, or at least each brew session. Keep them in an opaque canister, preferably one that lets the air out but not in (the expensive mechanical twist vacuum ones are not necessary). For the love of everything holy, NOT the fridge or freezer!
THINGS YOU MIGHT WANT TO BUY: Knockbox--doesn't have to be a pricy one. (You don't want to accidentally dump your portafilter's basket into the sink or worse, the trash can or compost pail). Spend $10 or so for a good tamper. (But let its weight do the work, and don't try to spin it). WDT needle and weighted leveler tools are overkill--as is a dosing funnel if you aren't using a Mazzer grinder with a doser (Newbies--if that sounds like gibberish, you aren't using one). The manual advises against using a blade grinder (that cheap "whirly" kind better suited to spices), and recommends a "grind type mill" (i.e., a burr grinder).
Don't get me wrong--this espresso won't be "God shots," nor "Third Wave" barista champ quality, no matter how mad your skilz. But pair it with fresh beans, filtered water and a good burr grinder (Baratza Encore or better) and with a little practice you will be rewarded with the real thing! For $99--just a little more than those "steam toys" that brew into glass carafes--if it lasts me a year, I'll be delighted. I won't be giving it heavy use once my prosumer machine comes home, but it will more than just "do."
EDIT 3/23/26: Decided to try steaming milk, to see if it’s controllable for microfoam. (My Andreja Premium is too powerful—heats the milk too fast after stretching (and even 2 seconds is too long to stretch before getting thick foam). Well, it will take a little patience to wait and then bleed off some water. But it is quite gentle and controllable. Do I want to use two machines (at opposite ends of the room) to make a drink with latte art? After all its shots are not as good as from my prosumer machine, which steams too powerfully. But it DOES what it’s supposed to.
