Best grill motor

Updated: 23 October 2026

You already have a gas barbecue with a standard 8 mm square spit, or you have measured that square, and the bracket is on the side. A search for the best grill motor still mixes in kits, hog-roast drives and battery motors. This page uses one criterion: the deepest amazon.co.uk review file among motor-only mains listings in our set that state that 8 mm drive. The [grill motor comparison](/hub/grills-and-barbecues/grill-motor) holds the full table, with row prices in GBP from 21 October 2026. We compared those listings and did not run a lab load test. If you have not measured the spit, start with the [grill motor buying guide](/hub/grills-and-barbecues/grill-motor/sub/grill-motor-buying-guide).

What “best” means on this page

“Best” here means the mains motor an 8 mm gas-grill spit can use, with the largest UK review count in this snapshot. On 21 October 2026 those three onlyfire mains files were 4.6 from 164 reviews, 4.4 from 159, and 4.4 from 103. Kits and an 80 kg hog-roast motor in the same results are a different purchase. A D-cell motor sold as extra quiet stays on the mains or battery grill motor page. A 5.0 from one review, on the YJINGRUI MX-S40 at about £49.99, is not that file. Our score of 92 is 4.6 scaled to 100, a marketplace rating, not a test-house mark.

The default mains motor

The top pick for that job is the onlyfire F-BRMA212-PE1-UK, B071L4GFJ6, at about £23.99. It states 220–240 V, up to 15 kg, a 5/16 inch (8 mm) square, an on/off switch and a 150 cm lead. The title claims a UK 3-pin plug, and the file has no photograph of the pins. It is not a laboratory winner. The mount is printed as 3 inch (7.6 mm). Sister listings print 3 inch (7.6 cm), so measure the bracket. Speed is not printed. Napoleon’s UK article suggests about 3 to 6 RPM, and that is not a specification for this motor. One UK review describes a plastic outer case. The table does not name a material.

When to spend more

Spend more when the case or the stated kilograms are the point. The stainless F-BRMA312-SS1-UK is about £26.72, the same 15 kg and 8 mm square, 4.4 from 159 reviews, with the mount printed as 3 inch (7.6 cm) and the case named stainless. The comparison marks that as best value: stainless for £2.73 more. Stay with B071L4GFJ6 if review count is the only criterion. The 18 kg step is F-BRMA102-SS1-UK at about £34.99, stainless, 8 mm, 4.4 from 103, for a balanced load above 15 kg. The 40 kg claim is the MX-S40 at about £49.99, with 2.7 RPM and 5.0 from one review. None of these mains rows prints an IP rating.

Who should not buy this default

Leave B071L4GFJ6 if the square is not 8 mm. The Cyprus-style onlyfire is a 6.4 mm drive, and the D-cell WPKD is 6.5 mm. A missing bracket is a reason to stop: this is a drive, not a kit of rod, forks and a side plate. If adding a bracket means drilling near the gas hose, do not. Fitting and the poultry check are on how to fit a grill motor. Leave it if you need a printed RPM. The adjustable 3.5 W onlyfire states 1.5–7 RPM and 9 kg. A battery motor can be right for a lighter job. It is not the best grill motor under this rule.

Common questions

What is a sensible default mains motor for an 8 mm spit?
In this set it is the onlyfire F-BRMA212-PE1-UK at about £23.99, with 4.6 from 164 reviews, up to 15 kg and an 8 mm square. The mount is printed as 3 inch (7.6 mm), speed is not printed, and the case is not in the technical table. Measure the bracket before you order.
Why not the listing with a 5.0 score?
The MX-S40 shows 5.0 from one review at about £49.99, and it leaves the mount and the plug claim blank while stating 40 kg and 2.7 RPM. One rating cannot describe the spread that 164 reviews can. Read it for a heavy stated load, not as the deepest UK file.
Is the stainless 15 kg motor worth more than the black one?
It is worth the extra £2.73 if you want “stainless” on the card. B072HPVRTB is about £26.72, 4.4 from 159 reviews, with the mount printed as 3 inch (7.6 cm). It is the weaker choice if your only criterion is review count. Neither row prints an RPM.
When is the 18 kg or the 40 kg motor the one to look at?
Look at the 18 kg stainless row, about £34.99 and 4.4 from 103 reviews, when the balanced load is above 15 kg and the spit is still 8 mm. Look at the MX-S40 when the card must say 40 kg and 2.7 RPM. Both are the wrong look if your spit is 6.4 mm.
Does “fits Weber” on a bullet mean it fits my grill?
It means the seller says the motor replaces motors on Weber and other brands, and that you should measure. One UK review of the about £23.99 motor described a Weber fit that stuck. We did not trial either motor on a Weber. A brand name in a bullet is not the measurement.
Why is there no RPM on the onlyfire mains rows?
Those three onlyfire mains rows do not print a speed. Napoleon’s UK article puts this style of cooking at about 3 to 6 RPM and stresses balance. That is guidance for the cook, not a figure we can paste onto the cards. If a printed speed is a condition, read the MX-S40 at 2.7 RPM or the adjustable row at 1.5–7 RPM.
