How Much Is My Bike Worth? UK Bike Valuation Guide 2025

What really determines your bike's value?

It’s a question that pops up eventually for every rider: “What’s my bike actually worth now?” The answer isn’t simple. Some folks think mileage is everything, but in truth, it's a mix of things—how well it's been looked after, how popular the model still is, and even what time of year you’re selling.

For example, a well-maintained bike with regular services logged will usually hold up well in price. On the other hand, a bike with low miles but signs of neglect might fetch less than expected. Add in things like regional demand and cosmetic condition, and it’s clear why no two valuations are ever quite the same.

Is there a "right" way to check your bike’s worth?

There’s no one-size-fits-all answer here, but there are definitely better ways to go about it. Some start with online bike valuation tools—they’re quick, sure, but often generalised. They won’t know about that brand-new tyre set you fitted last month or the service you just had done.

A better approach is to look at what similar bikes are going for locally. Not just asking prices—actual sold listings. Try to find ones with similar mileage and age. That’ll give you a truer sense of what people are willing to pay right now, rather than what sellers hope to get.

Is part exchange a smart move—or just the easy option?

Trading your bike in can feel like the path of least resistance. No faff with photos or buyers ghosting you last-minute. If you’re planning to upgrade, it’s often just more convenient. But it’s not always the best move if you want the highest return.

With part exchange, you’re likely to get a bit less for your current bike than if you sold it privately—but then again, you're saving time and effort. It really comes down to priorities: do you want top money, or do you want it done and dusted?

Do "we buy any motorbike" services actually deliver?

They’ve become more common in recent years. The idea is simple—enter your bike’s details, get a quote, and let someone else deal with the rest. These services offer an alternative to private selling, especially when you don’t have the time (or patience) to go the usual route.

That said, you’ll want to read the fine print. Some buyers say we buy any motorbike, but once they see it in person, the offer changes. Be upfront about the bike’s condition and set realistic expectations. It can be a handy option—but only when you go in with both eyes open.

What do you need before handing the bike over?

You’ll want your paperwork in order. That means the logbook (V5C), any MOT certificates, service records if you have them, and receipts for recent work. If you've got spare keys or original parts, include those too—it all helps.

Even a simple thing like giving the bike a clean before a viewing can nudge the offer up a bit. It’s not about hiding anything, but it does show that you’ve cared for it. First impressions still matter, even when selling machines.

Do upgrades and mods increase or decrease value?

Depends who you ask. Some buyers love a few extras—heated grips, luggage, improved suspension. But others see mods as a red flag, especially if they look home-done. If you've made changes, keep the original bits where possible. That way, buyers who want a stock setup won’t walk away.

It's also worth noting that some performance mods can impact insurance or make a bike harder to resell. So while you might love that aftermarket exhaust, don’t expect it to bump the price up much—unless you find a buyer who’s after the exact same thing.

What are the biggest mistakes sellers make?

Pricing too high is probably top of the list. It’s easy to let emotion or pride get in the way. Just because you paid £6,000 three years ago doesn’t mean it’s still worth £5,500 now. Be honest with yourself—and the market.

Another common one is poor presentation. Dirty bike, vague description, or blurry photos? That’ll drive potential buyers away. Even if you’re using a buy any bike service, tidying it up shows care and might help your chances of getting a decent offer.

Does timing play a role in how much you get?

Absolutely. You’ll generally have better luck selling between March and September. That’s when the biking season kicks in, and demand tends to rise. Trying to offload in the depths of winter? Might be tougher unless you’re selling a winter-friendly commuter.

It’s not just weather either. Sometimes, economic shifts push more buyers towards used bikes instead of brand-new ones. Keeping an eye on trends can help you catch the market at the right moment.

Final Thoughts

Getting a fair bike valuation takes more than guessing or picking a random number. It’s about knowing your bike, reading the market, and figuring out what works best for your situation.

Whether you're parting with it to upgrade, decluttering the garage, or just curious what it’s worth—taking the time to get it right matters. Companies like BigMoto make it easier by offering both we buy any motorbike and part-exchange options that suit different riders’ needs. They don’t just buy any bike—they make the process simpler when it’s time to move on.
