The new Burn FST from Wilson features Fast Speed Technology – an octagon frame geometry and headlight balance that allows the racket to move fast through the air for increased racket head speed at any angle of attack. That’s the big change in this new edition, but the rest of the tech in the Burn is as effective as ever.

Parallel Drilling expands the sweet spot size, and an 18x17 string pattern provides forgiving feel and control. Spin Effect technology increased ball RPM without needing to change your swing, while the X2 Ergo customisable handle shape creates optimal personalised feel.

The Burn FST will be used by Juan Martin Del Potro and is perfect for players who build their game around their groundstrokes, battle from the baseline and win with consistency and patience.

The Wilson Burn FST is compatible with the new Sony Smart Tennis Sensor, which records accurate shot data alongside real-time video.

Headsize 99 in. sq.
Weight (U) 299g / 10.5oz

Balance (U) 30.5cm / 12 pt HL

Please be advised that this racket will come strung unless the image displays otherwise.

Please note that all Wilson Burn rackets come without a protective head cover.


Our demo programme is easy: follow the simple instructions below and test any racket for two weeks!

1. Click “Demo now” on the rackets you wish to demo. You can demo a maximum of two rackets at a time.
2. Pay for the rackets as normal. You’ll receive them within the standard timeframe of the delivery option you select.
3. Try ’em out!
4. Return the rackets in good condition. You’ll need to pay postage.
5. We’ll refund the price of the rackets (minus delivery) when we receive them back from you. Or, if you liked a racket so much you want to buy it for real, let us know and we’ll send you a brand new one at no extra cost.


How much is it?
We initially charge your credit/debit card for the full price of the rackets plus delivery, and you’ll also have to pay for return delivery. When we receive the rackets back from you, we’ll refund the price of the rackets minus our initial delivery charge. So, in effect, the overall cost to you is just the postage for the rackets’ round trip.

How long can I demo a racket for?
A maximum of two weeks.

Can I keep the rackets I demo?
No, we have dedicated demo rackets, so please send them back in good condition ready for the next person.

How should I return the rackets?
Send the rackets back to us using a courier of your choice. You’ll need to pay postage, and you must make sure you have a tracking number for the parcel – use recorded delivery and ensure that the rackets are insured to their full value.

But what if I decide I like a racket?
Return the demo rackets as normal, including the completed Dispatch Note to let us know which racket you liked, and we’ll send you a brand new one at no extra cost.

When might I not get my money back?
If you return the demo rackets in what we deem to be a non-satisfactory condition, we reserve the right to withhold your refund. Rackets MUST be returned in a condition that allows us to demo the racket to another customer.

Measuring Your Grip Size

Choosing the right grip size is a vital part of playing tennis. The right grip size will make your racket feel natural and comfortable.

Use a ruler and measure (in inches) from the crease fold in your hand, to the top of your ring finger. Please see table below:

Grip Size
USA (inches)
4 1/8
4 2/8
4 3/8
4 4/8
4 5/8

Note: It is always better to go for a smaller grip size, as you can easily increase your grip size with over grips.
