The Cheapest Inline-Four Superbikes You Can Buy Today

We’ve all daydreamed about owning an inline-four superbikes at some point in time. They still remain the top dogs for serious performance, offering high-spec underpinnings and power-to-weight ratios that can shame million-dollar supercars for fun. These bits also make them quite pricey, though. Plus, these aren’t mass-market sports bikes, so we rarely see aggressive pricing strategies in the segment. On that note, here are some of the cheapest inline-four superbikes on the market in 2026. Understandably, the list is dominated by Japanese bikemakers.

Suzuki GSX-R1000

Price: $16,399

Why Toyota’s Biggest Hybrid SUV Now Costs Lexus RX Money to Own

With the new wave of Suzukis (like the DR-Z4S and GSX-8TT) boasting eye-watering prices, the new GSX-R’s MSRP feels like a pleasant surprise. The superbike now starts from just $16,399–$100 less than before. To boost the value, there are some solid updates in the GSX-R’s electronics and engine departments. The former now has updated algorithms for the traction control, slide control, engine brake control, wheelie control, and launch control, while the latter has new internals to boost high-performance reliability. That means the new Gixxer should be even more upgrade- and abuse-friendly.

Suzuki Cycles

As before, there’s also a GSX-R1000R on sale. It costs $17,939, justified by higher-spec Showa suspension and a two-way quickshifter. At the top of the segment sits a new GSX-R1000RS variant with carbon fiber winglets. All three versions come in three special 40th anniversary liveries, inspired by the OG Gixxers of the past. No other bike in the segment has such a vibrant spread of liveries.

Honda CBR1000RR

Price: $17,099

Honda

What you’re looking at is one of the friendliest inline-four superbikes on sale. What might bum you out, though, is the fact that this is essentially the same bike from 2017. And it’s totally fair if you’d rather pick a used example from a few years ago to save more money. Despite no updates, this is still a brilliant bike in every way.

Honda

That’s thanks to a combination of a smooth pure-bred inline-four engine, low weight (under 440 pounds), accessible ergonomics, and brilliant reliability over the years. You also get a fairly modern electronics package that checks all the necessary boxes. You get:

• Five-axis IMU
• Throttle-by-wire
• Nine-level traction control system
• Rear lift control
• Wheelie control
• Cornering ABS
• Engine power modes
• Engine braking modes

The affordable $17,000 MSRP only feels like a cherry on the cake then. You can further save $100 by picking the MY26 bike for $16,999.

Kawasaki Ninja ZX-10R

Price: $16,999

Kawasaki

The ZX-10R has had a sizable update for this model year. That’s brought a new design, minor engine tweaks, and updated electronic aids. Topping these is an Ohlins steering damper and retuned settings for the Showa suspension. All these things usually mean a sizable price hike (the damper alone can cost around $400). Yet, Kawasaki has somehow surprised us all by slashing the MSRP to $16,999 (down from $17,799).

The only bummer is the drop in peak power. The new bike makes 190 horsepower, down from 196 ponies on the 2025 model. To make matters worse, the weight has gone up by a few pounds. So you’re looking at a worse power-to-weight ratio than before. Much of that is due to the tightening emission norms that add weight and choke the engine further each year.

Yamaha YZF-R1

Price: $19,199

Yamaha

Yamaha has pulled the YZF-R1’s plug in the international market. But it remains on sale in the US, priced at $19,199. That makes it one of the priciest inline-four superbikes from Japan today and priced really close to the more modern European rivals. What you get here, however, is one of the most unique inline-four experiences. This is courtesy of the crossplane crankshaft setup—something no other inline-four superbike has today. Accordingly, the power delivery is rowdy, and the exhaust note sounds angry.

Aside from this, the YZF-R1 also has minor updates in its recent avatar. The crown jewels are the updated KYB suspension and Brembo Hypure front brakes, while the new front wings bring a pinch of modernity to the design as well. A special shout also goes to the new 70th Anniversary colorway that’s straight up gorgeous. It costs $500 more, though.

BMW S 1000 RR

Price: $19,975

BMW

Just a few years ago, the S 1000 RR’s MSRP was hovering in the $18,000 ballpark. Now, the price has steadily climbed close to $20,000 without any packages or colors. Adding the latter takes the price to beyond $25,000 faster than the bike reaches 62mph. Despite the price, the S 1000 RR is one of the most complete superbike packages on the market. So the moolah is justified in a way.

BMW

The inline-four engine has ShiftCam to keep up with the V4 dominance, the underpinnings boast learnings from the WSBK-winning M 1000 RR, and the electronics package is one of the most sophisticated out there. As part of the latest updates, BMW has also given the RR a WSBK-derived quick turn throttle and larger-than-ever front wings. The latter offers over 50 pounds of downforce at 186 miles per hour–around 25 more than the previous model.

Honda CBR1000RR-R Fireblade SP

Price: $28,999

Honda

Yes, this is a Honda CBR costing more than a Ducati Panigale. But it’s no ordinary CBR. This is the flagship homologation special, loaded with exotic parts from head to toe. So electronic Ohlins suspension, Brembo Stylema R calipers, and race-derived electronic aids are all standard equipment here. It’s worth noting that the Fireblade SP was the first superbike to feature the new EC3.0 Ohlins suspension (most bikes still have the EC2.0).

Honda Powersports

Topping things is a 1000cc four-cylinder engine with internal tech derived straight from the MotoGP bike: the RC213-V. The latest updates bring a higher compression ratio, shorter gearing for more punch, and a new Akrapovic road-legal exhaust. That helps produce 214 horsepower–the highest output for a naturally aspirated inline-four engine today. Oh, and the RR-R is also famous for being able to hit 186mph in just the fourth gear!
