Motopressor pocket pump & 12V outlets.

Updated: Jul 28, 2019

The Motopressor pocket pump (pictured above) is a great little unit, and it seems that nine out of ten riders that carry a 12v pump have one.

And for good reason, they're small, light and pump fast, fully inflating a dead flat tyre in a just a couple of minutes.

Here's the details and specs as listed on Rocky Creek Designs website.

MotoPressor Pocket Pump

This is a great little pump. ULTRA compact, this stripped down pocket pump weighs in at only 590g and fits in the palm of your hand.

Built around a custom modified 12V inflator. What it lacks in looks, it makes up for in performance and functionality – which is what you really need when you’re stranded in the middle of nowhere.

MotoPressor Pocket Pump has a 63cm long inflator hose, with a screw on delivery valve that fits all bikes.

A long 2.65m power cord comes with two adaptors: a direct connect for your battery and alligator clips, both with SAE connectors. 

All this packs small into the included heavy duty neoprene pouch.

The Pocket Pump will pump a front tyre (120/70 19) from flat to 35 psi in around 2 minutes 58 seconds and a rear tyre (170/60 17) to 35 psi in around 4 minutes 30 seconds

(Tests run on a 2015 BMW R1200GS LC). 

MotoPressor Pocket Pump is capable of pumping over 100 psi! 

Real World

The pump does exactly what it's meant to, and we've found it actually works faster than expected, with a 90/90/21 and 90/100/21 front tyre, it took a little under 2 minutes to reach 30psi, and around 4 mins on the 150/70/18 rear, both with Ultra Heavy Duty tubes.

As much as we try and look after our gear, abuse or just general damage is inevitable. The only things to look out for really, is to check the shield is clear of the plastic gear and try and place the pump on it's pouch or a rag when using it, it just helps keep the dirt and muck out from between the gears and wearing them prematurely.

There's no inline fuse on the wiring to the pump, so make sure you run from a fused supply, and if you're running it off a battery jump pack, it might be a good idea to fit an inline fuse just to be safe.

The pump draws more than you might expect, so before pugging it in to your bikes 12V outlet or SAE connector, check the circuit rating and fuse, even some new bikes accessory outlets are rated lower than what a pump will draw.

0 air and pump running: draws 8A

0 to 40psi: draw is 13A

Run a 15A or 20A fuse and make sure your wiring is compatible, if it's not, upgrade it.

If you're not sure, or want to keep the higher draw items separate from your factory harness, wire a new fused aux outlet socket or SAE connector directly from the battery.

On the Honda, we've fitted a better quality 12V outlet in place of the factory one and wired to suit a higher draw, as well as an easy accessible SAE plug.

The SAE plug runs the Motopressor pump and is also handy for a battery charger or tender when the bike sits in the garage.

Before hooking up a pump or battery charger to an existing SAE connector, it's also a good idea to check the polarity as seen at the end of this post about jump packs.

And for $5 from Woolies, the jump pack, pump and other pieces live in a zip up lunch case in the pannier, simple and cheap.

Hope this helps, see you out there!
