Tank Bag Gear Review

If you’ve followed my motorcycle adventures, you already know I’m a bit of a gear junkie and a MacGyver. I’ve learned one thing: the right gear can make a hell of a difference! And when it comes to tank bags, sometimes bigger isn’t necessarily better.
Today, I’m taking a look at two great motorcycle tank bags from Chase Harper USA — the 450 and 650 models. Both have their advantages, both are built with practicality in mind, but after comparing them, I’ve got a favorite.
The Chase Harper 450 gets my vote!
Chase Harper 450 — Small, Simple, and Gets the Job Done!
There’s something to be said about a tank bag that doesn’t try to do too much. The Chase Harper 450 is a compact, low-profile tank bag with a clear map pocket on top, multiple zippered compartments, and just enough storage for the essentials, food and what nots. For my style of riding, that’s exactly what I’m looking for.
The bag measures approximately 12 inches long, 9 inches wide, and 4 inches tall and expandable.
What I particularly like is the clear map window. For long-distance motorcycle adventures, especially rides where traditional navigation or paper directions come into play, having information directly in front of you is extremely convenient.
No digging through saddlebags, no stopping every 20 minutes to find something, and no turning the motorcycle into a rolling storage closet. It’s compact enough to keep the tank area relatively uncluttered while providing convenient access to the things I use most.
What I like about the 450:
- Compact, low-profile design
- Clear map pocket for directions
- Convenient zippered storage
- Less bulk around the fuel tank
- Practical for everyday riding and endurance adventures
- Approximately 6.8 L
For me, the 450 strikes a nice balance between convenience and simplicity.
Chase Harper 650 — More Room for More Stuff!
Now, don’t get me wrong. The Chase Harper 650 is another great option, especially for riders who prefer additional storage.
The 650 takes things up a notch with a larger, but taller design, multiple storage compartments, an exterior mesh pocket, and a bungee-cord system on top for securing smaller items.
Depending on the version, published dimensions are approximately 12.5–13 inches long, 9–9.5 inches wide, and 5–7 inches tall. Approximately 13 L
That’s a noticeable increase in storage compared with the 450.
The 650 is especially appealing for touring riders who want to keep more of their everyday essentials close at hand without constantly opening their saddlebags.
The external storage features are a nice touch, too. Having additional places for small items can make organizing your gear considerably easier.
But here’s where personal preference comes into play.
More storage also means more bulk.
And when on my Road Glide, I prefer keeping the area directly in front of me as clean and uncomplicated as possible.
Why I Prefer the 450
When you’re riding 1,000 miles in a day, or sometimes considerably more, you start appreciating equipment that does its job without getting in the way.
My philosophy with motorcycle gear has always been pretty straightforward: functionality first, unnecessary bulk last.
The 450 gives me convenient storage without taking up more real estate than necessary.
I don’t need to carry half my garage on the gas tank. I’ve already got saddlebags and other luggage for that!
What I want from a tank bag is quick access to my important stuff.
The 450 fits that role nicely.
That doesn’t make the 650 a bad choice. Far from it. If you’re someone who prefers additional storage for longer trips, the 650 might actually be the better option. I mean I do own both to make that decision based on my plans.
It really comes down to your riding style and how much you want within arm’s reach.
A Few Things Worth Considering
Regardless of which model you choose, there are a few things I always pay attention to when using tank bags.
First, make sure the mounting system is secure. You don’t want your bag shifting around while riding, especially at highway speeds or during aggressive turns.
Second, keep the bottom of the bag and the fuel tank clean. Road grit trapped between the two can eventually scratch your paint. Hence my blue painters tape.
Third, check that the bag doesn’t interfere with the handlebars, controls, fuel cap, or your ability to move comfortably on the motorcycle.
And finally, don’t assume a tank bag is completely waterproof. If you’re riding through hours of heavy rain, protect sensitive electronics and important documents with additional waterproof storage.
Final Thoughts — Two Great Bags, One Clear Favorite!
Chase Harper has been making motorcycle luggage for decades, and I appreciate the straightforward, practical approach behind these designs.
It’s the one that works for me and perhaps for you, mile after mile.
