Choosing the right first ATV for your young rider is a massive decision. You want something safe, reliable, and perfectly sized to build their confidence without being overwhelming. It’s a balance between a machine they can handle now and one they won’t outgrow in a single season.
We promise this guide will give you the expert insight you need to solve that problem. We’re going to break down the real-world differences between these two fantastic youth ATVs, going beyond the spec sheet to give you practical advice from years of experience.
In this comprehensive can am ds 70 vs 90 guide, we’ll compare engine performance, critical safety features, rider ergonomics, long-term maintenance, and overall value. By the end, you’ll know exactly which machine is the perfect fit for your budding off-roader.
At a Glance: Key Spec Showdown
Before we get into the nitty-gritty, let’s lay out the core differences in a simple format. Think of this as your cheat sheet for the main distinctions between the two models.
- Engine Displacement: The DS 70 has a 69cc 4-stroke engine, while the DS 90 has a larger 89.5cc 4-stroke engine. This is the primary performance difference.
- Recommended Age: Can-Am recommends the DS 70 for riders aged 6 and up, and the DS 90 for riders aged 10 and up. This is a critical safety guideline.
- Top Speed: The DS 70 is factory-limited to 15 mph (24 km/h), while the DS 90 is limited to 30 mph (48 km/h). Both can be further restricted by parents.
- Transmission: Both models use a simple and effective Continuously Variable Transmission (CVT) with Forward, Neutral, and Reverse. No shifting means more focus on riding.
- Suspension: Both feature a similar Independent A-Arm front suspension and a swingarm rear, providing a stable and comfortable ride for young riders on the trail.
Engine and Performance: Is Bigger Always Better?
The number on the side of the plastic is the biggest point of debate in the can am ds 70 vs 90 discussion. The 20cc difference might not sound like much, but it creates two very different riding experiences for a young person.
The DS 70’s 70cc Engine: The Perfect Confidence Builder
The DS 70 is all about smooth, predictable power. Its 70cc engine is designed to be incredibly manageable, preventing the “whiskey throttle” that can scare new riders.
The power delivery is linear and gentle. This allows a child to learn the fundamentals of throttle control, braking, and steering without the machine ever feeling like it’s going to get away from them. It’s the ideal platform for building a strong, safe foundation in off-roading.
Think of the DS 70 as the ultimate learning tool. It has enough pep to be exciting on backyard trails but not so much that it becomes intimidating. This is one of the key benefits of can am ds 70 vs 90 for younger or more timid riders.
The DS 90’s 90cc Engine: A Little More Room to Grow
The DS 90 steps things up a notch. That extra 20cc provides noticeably more torque and a higher top speed. It feels more spirited and is better suited for riders who already have some experience or are naturally more confident.
This machine is perfect for the 10+ age group that Can-Am recommends. It can tackle small hills with more authority and keep up better on open family trail rides. It’s the logical next step up, or a great starting point for a slightly older beginner who has the size and maturity to handle the extra performance.
Safety First: A Deep Dive into Can-Am’s Youth Features
For any parent, safety is non-negotiable. Can-Am understands this, and both the DS 70 and DS 90 are packed with features designed to give you peace of mind while your child learns the ropes. These features are some of the most important can am ds 70 vs 90 best practices to understand.
The Built-in Throttle Limiter: Your Control Panel
This is arguably the most important safety feature on both models. A simple screw located on the throttle housing allows you to physically limit how far the throttle lever can be pushed.
You can dial the top speed down to a walking pace for their first few rides. As they gain skill and confidence, you can gradually open it up. This feature alone is a massive benefit, giving you complete control over their learning curve.
Pro Tip: When you first get the ATV, set the limiter to the most restrictive setting. In an open, flat area, walk alongside your child as they ride to gauge their comfort. Adjust it in tiny increments only when you are both 100% confident.
Electric Start with a Kick-Start Backup
The push-button electric start makes getting going easy and frustration-free for kids. There’s no complex starting procedure to remember.
However, we all know batteries can die. The inclusion of a traditional kick-start backup is a fantastic feature. It ensures you’re never stranded on the trail and provides a great opportunity to teach your child a little bit about how engines work.
Full Floorboards and Rider Protection
Unlike some youth ATVs that use simple foot pegs, the DS series features fully integrated floorboards with raised heel guards. This design provides a large, stable platform for the rider’s feet.
More importantly, it helps prevent their feet from slipping off and potentially getting caught under the rear tires—a huge safety advantage.
The Can Am DS 70 vs 90 Sizing Guide: Fit is Everything
An ATV that is too big or too small is an unsafe ATV. Proper rider fit allows for control, comfort, and the ability to shift weight effectively, which is a core skill in off-roading. Here’s how to can am ds 70 vs 90 fit your child correctly.
Who is the DS 70 For? (Ages 6+)
The DS 70 is built on a slightly smaller chassis. It’s perfect for riders in the 6-to-9-year-old range. The seat height is lower, and the handlebars are positioned for a shorter reach.
A smaller rider on a DS 70 will feel in command of the machine, not like they are just hanging on. This builds confidence and allows them to learn proper riding technique from day one.
Who Should Ride the DS 90? (Ages 10+)
The DS 90 is physically a bit larger to accommodate taller riders, generally those 10 and older. The handlebars are slightly higher and wider, and the distance from the seat to the floorboards is greater.
Putting a 10-year-old on a DS 70 might feel cramped, hindering their ability to move around and control the ATV. The DS 90 gives them the space they need to ride comfortably and safely for years.
The Practical “Fit Test” You Must Do
Don’t just rely on age recommendations. Have your child sit on both models at a dealership if possible. Here’s what to look for:
- Reach the Controls: Can they comfortably reach the handlebars with a slight bend in their elbows? Can their thumbs easily operate the throttle and their fingers reach the brake levers?
- Feet on the Floorboards: Their feet should sit flat and securely on the floorboards with their knees bent at a comfortable angle.
- Shift Their Weight: Ask them to stand up slightly and lean from side to side. They should be able to do this easily without feeling stretched or off-balance.
Maintenance and Common Problems with Can Am DS 70 vs 90 Models
This is where our can am ds 70 vs 90 care guide comes in. Thankfully, both of these machines are incredibly reliable and easy to maintain. They are built with simple, robust air-cooled engines that can stand up to years of use with basic care.
Routine Checks: Your Pre-Ride Ritual
Instill good habits early. Before every ride, teach your child to perform a quick “T-CLOC” check:
- T – Tires & Wheels: Check for proper air pressure and any damage.
- C – Controls & Cables: Make sure the throttle snaps back and the brake levers move freely.
- L – Lights & Electrics: Test the keyed ignition and neutral light.
- O – Oil & Fuel: Check the engine oil level and make sure there’s fresh fuel in the tank.
- C – Chain & Chassis: Look at the chain for proper tension and check for any loose nuts or bolts.
The Most Common Problem: Carburetor Gunk
The single most common issue with these small ATVs is a clogged carburetor from stale fuel. The tiny jets inside are easily gummed up, leading to hard starting or poor running.
The Fix: This is a key part of any discussion about common problems with can am ds 70 vs 90. Always use a fuel stabilizer (like Sta-Bil or Sea Foam) if the ATV is going to sit for more than a few weeks. If possible, use ethanol-free gasoline. If the carb is already clogged, it will need to be removed and professionally cleaned.
Sustainable Ownership Tips
Thinking about a sustainable can am ds 70 vs 90 approach means maximizing its life. Proper maintenance is also the most eco-friendly can am ds 70 vs 90 practice. A well-tuned engine burns cleaner, and regular checks prevent fluid leaks on the trail. Keeping the battery on a tender during winter extends its life, reducing waste.
Frequently Asked Questions About the Can Am DS 70 vs 90
Can I make a DS 70 faster once my kid is ready?
No. While there are aftermarket parts, these machines are designed to operate within their factory limits. The safest and most reliable way to get more performance is to sell the DS 70 and move up to the DS 90 when your child has the appropriate size and skill.
What safety gear is essential for a young rider?
This is non-negotiable. At a minimum, every rider needs a DOT-approved helmet that fits properly, over-the-ankle boots, gloves, goggles, and long pants/sleeves. A chest protector is also highly recommended.
How do I adjust the throttle limiter screw?
It’s very simple. On the thumb throttle housing, you’ll find a small screw. Turning it IN reduces the distance the throttle can be pushed, lowering the speed. Turning it OUT increases the available throttle. Refer to your owner’s manual for a precise diagram.
Are parts for the DS 70 and DS 90 easy to find?
Yes. As a major manufacturer, BRP (Can-Am) has a vast dealer network. Common maintenance parts like air filters, oil, spark plugs, and brake components are readily available.
The Final Verdict: Which One is Right for Your Family?
The choice in the can am ds 70 vs 90 debate comes down to one simple factor: your rider. Both machines are excellent, safe, and reliable.
Choose the Can-Am DS 70 if you have a younger rider (6-9), a first-time rider who is more cautious, or a smaller child. Its gentle power and smaller frame are perfect for building a strong, confident foundation.
Choose the Can-Am DS 90 if your rider is older (10+), has prior experience on a smaller machine, or is taller and ready for a bit more performance. It offers the room to grow that will keep them happy on the trails for years.
Don’t rush the decision. Putting a child on a machine that’s too big or too powerful is the fastest way to scare them away from the sport. Get the fit right, invest in quality safety gear, and get ready to make some incredible family memories out on the trail.
