However, the actual out-the-door price typically runs $1,000-1,800 higher after factoring in dealer fees, documentation charges, freight, assembly, and taxes.
Pro tip: Dealerships often have more flexibility on pricing for previous model years or during the off-season (late fall through winter in many states).
Kawasaki Ninja 400 Warranty Coverage
Youll get a 12-month limited warranty. This factory warranty covers defects in materials and workmanship but doesn’t include normal wear and tear.
Extended warranties are available through Kawasaki (Kawasaki Protection Plus) or third-party providers, typically extending coverage to 24, 36, or even 48 months. These can cover mechanical breakdowns beyond the factory warranty period but read the fine print carefully, as not all components may be covered.
Dealer Fees to Expect
When buy kawasaki ninja 400, you’ll likely encounter several dealer fees:
- Destination/freight charge: $400-500
- Setup/assembly fee: $200-400
- Documentation fee: $100-300
- Title and registration: Varies by state
Some of these fees are negotiable, particularly setup and documentation fees. Don’t be afraid to ask the dealer to reduce or waive certain charges, especially if you’re paying in cash or financing through them.
Kawasaki Ninja 400 Insurance Costs
Insurance for the motorcycle is relatively affordable compared to larger sport bikes. For riders with clean records, full coverage typically ranges from $400-800 annually (most riders are paying around $300-$400 per year ($25-$33 per month) to insure their Ninja 400) depending on your age, location, riding history, and chosen deductibles.
Many insurance providers offer discounts for completing motorcycle safety courses, having multiple policies, or installing anti-theft devices.
Financing Options
Most dealerships offer financing through Kawasaki’s own financial services or partner banks. Typical terms range from 36-72 months, with interest rates varying based on your credit score.
Credit unions often provide more competitive rates than dealer financing, so it’s worth shopping around before walking into the showroom. Many riders save hundreds or even thousands in interest by securing pre-approval from their bank or credit union.
Standard Accessories
The Ninja 400 comes fairly well-equipped from the factory with LED headlights, a digital/analog combination instrument panel, and a rear seat cowl (on some models).
However, many dealers include additional accessories as incentives, such as frame sliders, tank pads, or even a first service. These can be valuable additions and are often worth negotiating for if not initially offered.
