Hey guys! Today, we're diving deep into the Pirelli MT21 Rallycross 120/80 tire. If you're an adventure rider or someone who loves hitting both the pavement and the trails, you've probably heard of this tire. But is it really worth the hype? Let's find out!

Overview of the Pirelli MT21 Rallycross

The Pirelli MT21 Rallycross is designed as a versatile tire, suitable for mixed terrain conditions. It’s a popular choice among dual-sport and enduro riders because it promises a good balance between on-road comfort and off-road grip. The 120/80 size is specifically tailored for a range of bikes, offering a profile that enhances both stability and maneuverability. Pirelli, as a brand, has a long-standing reputation for quality and performance, so expectations are naturally high when considering the MT21 Rallycross.

Key Features and Technology

One of the standout features of the Pirelli MT21 Rallycross is its knobby tread pattern. This design is aggressive enough to bite into loose surfaces like dirt, gravel, and sand, providing essential traction when you venture off the beaten path. The knobs are widely spaced to facilitate self-cleaning, preventing mud and debris from packing in and reducing grip. The tire’s compound is formulated to offer durability without sacrificing grip, ensuring it can withstand the rigors of both on and off-road riding. Additionally, the carcass construction is engineered to provide a comfortable ride on the tarmac while remaining robust enough to handle impacts and abrasions off-road. This combination of features makes the MT21 Rallycross a compelling option for riders who demand versatility from their tires.

Target Audience and Riding Conditions

The Pirelli MT21 Rallycross 120/80 is ideal for riders who split their time between paved roads and off-road trails. Whether you're commuting during the week and exploring dirt roads on the weekend, or embarking on longer adventure rides with varied terrain, this tire aims to deliver consistent performance. It’s particularly well-suited for lighter to middleweight dual-sport bikes, where its size and weight complement the bike's handling characteristics. Riders who appreciate a tire that offers a reasonable lifespan without compromising grip will find the MT21 Rallycross a solid choice. It's also a favorite among those who participate in rally events or off-road touring, where reliability and versatility are paramount. Keep in mind that while it performs admirably in many conditions, it's not a dedicated off-road tire, so extreme mud or very technical terrain might require a more specialized option.

On-Road Performance

Okay, let's talk about how the Pirelli MT21 Rallycross performs on the road. Let’s be real, knobby tires aren't usually known for their amazing on-road manners, but the MT21 Rallycross actually does a decent job. The engineers at Pirelli have clearly put some thought into making this tire tolerable, even enjoyable, on pavement.

Handling and Stability

For a tire with such an aggressive tread pattern, the Pirelli MT21 Rallycross offers surprising stability on paved surfaces. It doesn't feel overly squirmy or unstable, even at higher speeds. Cornering is predictable, though you'll definitely notice the difference compared to a street-oriented tire. You'll need to lean a bit more and be smoother with your inputs, but it holds its line well. The tire's profile is designed to provide a reasonably large contact patch, which helps with stability and grip on the road. Overall, it's a compromise, but one that's well-executed for a dual-sport tire.

Noise and Vibration

One of the trade-offs with running knobby tires on the road is the inevitable noise and vibration. The Pirelli MT21 Rallycross is no exception. You'll definitely hear a noticeable hum, especially at higher speeds. The vibration is also present, though it's not excessive. It's something you get used to over time, but it's worth considering if you do a lot of highway riding. Some riders find the noise annoying, while others see it as part of the adventure. It really comes down to personal preference. If you prioritize a quiet and smooth ride above all else, this might not be the tire for you. However, if you're willing to tolerate some extra noise and vibration for the added off-road capability, the MT21 Rallycross is a reasonable compromise.

Wet Weather Performance

Wet weather performance is where the Pirelli MT21 Rallycross shows some limitations. Like most knobby tires, it doesn't offer the same level of grip as a dedicated street tire in wet conditions. The widely spaced knobs can struggle to clear water quickly enough, leading to reduced traction and increased risk of hydroplaning. It's crucial to be extra cautious when riding in the rain, reducing your speed and avoiding sudden maneuvers. While the compound does provide some grip, it's still significantly less than what you'd experience with a tire designed specifically for wet roads. If you frequently ride in wet conditions, you might want to consider a more street-oriented dual-sport tire, or be prepared to adjust your riding style accordingly when using the MT21 Rallycross.

Off-Road Performance

Now, let's get to the really exciting part: off-road performance! This is where the Pirelli MT21 Rallycross is designed to shine, and it largely delivers. The aggressive tread pattern and durable construction make it a capable companion when you leave the pavement behind.

Traction and Grip

The Pirelli MT21 Rallycross truly excels in providing superior traction and grip across a variety of off-road terrains. Whether you're navigating loose dirt, gravel paths, or sandy trails, the tire's design ensures a confident and secure ride. The widely spaced knobs effectively bite into these surfaces, offering reliable traction that inspires confidence, even in challenging conditions. This is particularly noticeable when climbing steep inclines or maneuvering through uneven landscapes. The tire's ability to maintain grip helps prevent slippage and ensures that your bike responds predictably to your inputs, making off-road adventures more enjoyable and less precarious. Riders appreciate the consistent performance, which allows them to focus on the trail ahead without constantly worrying about losing control.

Handling in Different Terrains

One of the most impressive aspects of the Pirelli MT21 Rallycross is its versatility across different terrains. In soft sand, the wide knobs provide enough floatation to prevent the tire from digging in excessively, allowing you to maintain momentum. On rocky trails, the robust construction and reinforced sidewalls help to resist punctures and damage, while the flexible carcass absorbs impacts, improving ride comfort. In muddy conditions, the self-cleaning properties of the tread pattern come into play, preventing the tire from becoming clogged and losing grip. While it's not a dedicated mud tire, it performs admirably in moderately muddy conditions. This adaptability makes the MT21 Rallycross a great choice for riders who encounter a variety of terrains on their adventures, eliminating the need to switch tires frequently.

Durability and Puncture Resistance

Durability is a key consideration for any off-road tire, and the Pirelli MT21 Rallycross is built to last. The tire features a robust construction with reinforced sidewalls that offer excellent puncture resistance. This is particularly important when riding on rocky or debris-strewn trails, where the risk of cuts and punctures is high. The tire's compound is also designed to resist wear and tear, ensuring a longer lifespan even under harsh conditions. Riders report that the MT21 Rallycross holds up well to extended off-road use, with minimal chunking or tearing of the knobs. While no tire is completely indestructible, the MT21 Rallycross strikes a good balance between grip and durability, making it a reliable choice for adventure riding and off-road touring.
