450NK (MY2024)

Light, Willing, and Cheap

The Machine's Character

CFMOTO's 450NK is a 449 cc parallel twin built to feel lively without asking much of you. Fifty horsepower arrives high in the rev range, at 9,500 rpm, so the motor wants to be worked rather than lugged. Around it sits a genuinely light 375 lb chassis, an upside-down fork, and a 31.3 in seat that keeps both feet close to the ground. ABS and traction control come standard. This is a budget-priced naked that leans on low weight and easy manners instead of outright muscle, and it lands squarely in the accessible, everyday end of its class.

Live with it and the appeal holds. It sips fuel at 49 mpg, costs little to run, and stays friendly in traffic and on a relaxed back-road loop. Newer riders and anyone stepping down to something manageable will feel at home fast. The honest catch is that the softness cuts both ways. Low-end grunt is thin, so you carry revs to keep pace, and the suspension gives you little to work with: the fork doesn't adjust and the rear offers only preload, so the tune you test is close to the tune you own. Ride it for what it is and it delivers.

The Voice of Experience

Portrait of NastyNils

The test ride

Swing a leg over and the low seat drops you into the bike rather than perching you on top, with high bars and a relaxed, passive stance that stays comfortable through a long stint. The first thing you notice is the sound: the twin's exhaust note is gritty and mechanical, deeper than a 449 cc motor has any right to be, and it gives the bike more personality than the spec sheet promises. Shifts land clean and positive, the ratios sensibly spaced. The dash is crisp and easy to read at a glance. Then you thumb the switchgear and the budget shows through in the plasticky buttons. One quirk stood out too: finding neutral at a standstill can take a second nudge. Nobody climbed off in a bad mood.

Rated point by point — where it earns its keep

My own 0–100 score for this bike against the class, area by area — the marker on each bar is the class average.

Push the pace and the chassis runs short of answers. The suspension is set soft, plush over broken tarmac but losing composure as speed rises, and with nothing to adjust at either end you live with the compromise you're handed. Brake hard into a corner and the fork visibly flexes just as I'm loading the front for reassurance, which had me backing off. Ask for a quick, sharp turn-in and the steering goes vague, wanting patient, deliberate hands instead of reacting when you need it.

This is where the bike quietly wins me over. Everyone I handed it to came back happy, no exceptions. It's predictable and never sets out to catch you off guard, and inside its natural range it's honestly good fun. What stays with me is the way it flatters whoever's aboard, sending you off feeling like a sharper rider rather than one being put to the test. For the crowd this bike is chasing, that counts.

The front brake is the part I leaned on least by choice. Pull the lever and the bite point is soft and vague, so I found myself guessing at how much stopping power I had rather than feeling it. The feedback stays wooden right where I want clarity most, and outright braking is short of what this class should deliver. Fine at a steady road pace, but ask it to shed speed with any authority and it leaves you wanting.

The gearbox is the piece I trust most on this bike. Every change lands clean and positive, and the ratios sit close enough that I'm dropped into the right one for whatever the road asks. The low seat is the other easy win, low enough for smaller riders yet roomy enough that a taller frame isn't folded up over a long stint. What soothes at a cruise turns against you the moment you get serious, though. You sit deep behind tall bars in a passive stance, relaxed right up until you try to shift weight onto the front and drive a bend, at which point the geometry stops cooperating. The switchgear lets it down too, cheap and dated under the thumb in a way that belongs on machines from a couple of decades ago. And the traction control nags at me: it trips well short of the genuine limit, blind to lean angle and defaulting to caution the second I press on.

There's real character waiting up top. Keep the twin spinning in the upper half of its range and it turns eager, pulling harder the further it climbs and rewarding a rider willing to work it. Drop below that and it's merely adequate; the low-end is thin, so short-shifting in traffic or rolling on in a tall gear leaves you waiting on drive that isn't there. The saving grace is the noise, gritty and mechanical and far deeper than the displacement has any right to give, which hands the motor a personality the numbers never promise.

There isn't a lot to weigh up in this column, so credit where it's due: the display. It's crisp, sensibly laid out, and takes no effort to read at a glance. On a machine where plenty of the smaller details feel rushed, the screen is clearly where the thought went, and it's the one component that flatly impressed me.

The Truth on the Street

This comes from years of keeping an ear to the rider community: messages to my inbox, talk at the track, and notes from owners. For the 450NK the sentiment lands on a consistent shape. The praise gathers around the engine, the value, and the low weight; the complaints circle back to the suspension and the riding position.

Where the praise gathers

The 449cc twin draws the most goodwill, riders calling it refined and easy to read through the revs, with a sporty voice to it. Value sits close behind, owners pointing to how much kit comes along for the price: color TFT, Bluetooth, LED lighting, adjustable levers. The low weight earns steady mention for how flickable it feels in tight corners and slow traffic, and plenty single out the styling, the V-shaped LED headlight and clean finish reading above the budget field.

The gripes that stick

The complaints are fewer and cluster in two places. The suspension is one: a non-adjustable fork and preload-only rear that riders say go underdamped when pushed hard or ridden two-up. The other splits by build. That long reach to the flat bars suits longer arms, leaves shorter riders stretching, and has some taller riders feeling cramped by day's end.

Known issues

  • Difficulty finding neutral when stationary

    drivetrainoccasional

    Some early‑mileage test bikes exhibited a reluctance to engage neutral when stopped; this may be related to the running‑in oil or clutch adjustment.

The 'Should I Buy It?' Score

Forget spec-sheet bragging. Here's who the 450NK is actually built for.

A scenic view of Angeles Crest Highway winding through rugged Southern California canyon terrain. Rocky mountainsides with golden earth tones frame the asphalt road with tight sweeping curves.

Best motorcycle for Angeles Crest?

If you chase precision on Angeles Crest, be straight with yourself: the soft suspension, thin midrange, and vague brakes cap you before your skill does. Fun for a mellow run, not for hard canyon pace.
