It's right for you if...
You’re an all-mountain rider who loves pinning steep descents and sketchy rock gardens. You want a bike that’s born to plough through the roughest stuff at full tilt, is fully capable of racing enduro, and doesn’t break the bank.
The tech you get
An aluminium frame built for harsh riding with a threaded bottom bracket, dual downtube guards, Knock Block 2.0 and 160 mm of travel with a RockShox Select+ shock and 170 mm Yari RC fork. Plus, a SRAM NX Eagle drive train and Line Comp 30 wheels that are already completely tubeless ready, including sealant.
The final word
It may be the most affordable Slash in the line-up, but don’t underestimate how fast it'll carry you down the mountain. You get a frame built for day after day of hard riding with a no-nonsense parts package that leaves enough cash in your pocket for enduro entry fees or a lift ticket to party laps.
The Walkthrough
favorite_borderWhy you'll love it
- It's equally at home between the tape and in the rugged wild – Slash excels at racing enduro, but it's ridiculously fun on gnarly trail rides, too
- A sleek internal storage compartment gives you a versatile spot to stow tools and gear
- We added a second down tube guard to better protect your frame from shuttle-related damage
- New, removable Knock Block has a bigger steering angle to keep cables and hoses safe without sacrificing turning radius
- Wider seat tube, wider dropper – the 34.9 mm diameter post is stronger, more durable, and moves up and down faster
‘Feels exactly right’
‘The Slash has a big-bike feel that makes it easier to charge into an unfamiliar trail, while retaining enough manoeuvrability to prevent it from feeling like overkill on mellower trails.’

Enduro Bike of the Year
Once the dust had settled, it was the Slash that managed to edge its way into the lead. Its ability to tackle the wildest terrain without flinching yet all the while retaining that reactive, lively feel really won us over.

‘A hell of a bike’
‘Slash is great on rough, bermed corners and it has been an absolute monster riding steeps. This is an easy bike to ride and everything felt very natural from the first drop in and I haven’t looked back since.’

Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.
Complete frame protection
Replaceable down tube guards protect the underside of your frame from rock strikes, trail debris and janky shuttle vehicles so you can forget about damage worries and focus on blasting the next run.
Internal frame storage makes it easy to ditch the pack and still carry your ride essentials.
Rapid Drive 54 rear hub
With 54 points of engagement, Rapid Drive gives you nearly instant acceleration instead of a clunky lag when you step on the pedals. You get smooth, immediate power to blast out of corners and hammer through the rough stuff. And that extra pedal ratchet adds control that can make all the difference when tackling a tricky climb.
Knock Block has your frame's back when things go wrong. It prevents your handlebars from spinning all the way around in a crash, so your hoses won't get yanked and your controls won't hit the top tube.

Complete Tubeless System
Tubeless Ready rims and tyres make it easy to ditch the tubes so you get better traction, fewer flats and less weight. You're ready to roll straight out of the box with the included TLR rim strips, valves and sealant.

Threaded bottom bracket
Slash is built for the hardest riding in the harshest conditions with a threaded bottom bracket that's more robust than press fit.
Oversized 34.9mm dropper post
Bigger is better. The oversized seat tube diameter gives more support and strength for longer travel droppers, and allows for more robust, durable internals that work faster.
