Mini pumps for Motorbikes?

Skill Magill

Could anybody recommend a mini pump (one that is small enough to fit in a back-box or under a saddle) that might be able to inflate a fairly big motorbike tyre to about 30 or so so psi?
I was thinking maybe a dual action one ie co2 cartridge and manual pump all in one.
Does such a thing exist?

Cheers guys

Not sure if a CO2 cartridge would be much use for the volume of a motorcycle tyre. A bicycle pump will work as the pressures are low enough, it will just be a lot of pumping. There are small air compressors that you can get.

if you need a portable pump and value your time pumping a motorbike tyre the Zefal HPX would probably be the best.
That has to be one of the strangest "dual purpose" requirements I've seen in a long time.

When I was driving motorbikes, a portable pump wasn't high on the list of things to carry. Slime would probably be a better investment. Does your insurer not have a "free" rescue call out service?

Not that I know of. I've pumped a car tire with a big bicycle track pump a few times and it's quite a workout. You'd be there for the day with one of those mini bike pump, and as fast as you'd pump it in, the air would be pi$$ing out the cause of the puncture in the first place.

There are plenty of motorbike specific fixes for flat tires, so I would venture to say that you're barking up the wrong tree looking at pushbike products. -Cans of tire-weld, tire-slime, or as I used to rely on - AA membership and a mobile phone . Rescued me a couple of times.

Cheers buts its not an option,this is for emergencies, when stranded on the side of the road, I have the bits and bobs to repair the puncture, but to re-inflate the tyre I'll need a small portable pump. I thought that a couple of co2's would inflate it to certain level, then finish it off with the hand pump?

If you're going to be using multiple canisters, then you might as well use them all the way. Canisters come in a couple of different sizes; what size tyres are we talking about (front and back, might as well calculate for two)?

Skill Magill

I'd say I would need 6 altogether, and that would be for both, (I've never seen that happen though), Idealy I't would have to have a connectors that the Lezyne pumps have, but with a normal (high pressure) pump too

I let some lad inflate his scooter tyre with my lezyne mini pump up in the feather beds a few months back.

He had a slow puncture and inflated it pretty quickly.

I don't know the relative sizes of scooter and motor bike tyres. Can't be more than a few times bigger, surely?

Skill Magill

I don't have the stamina to be using a mini pump to reinflate a flat, thats why I'd like a dual pump (?) to take the sting out, the co2 to inflate it, and then use the hand pump part of it to get the correct pressure?

Do not even attempt to consider this, extremely dangerous on a tubeless motorcycle tyre.

Mini CO2 cylinders are available as are the pumped liquid aerosol types like slime etc.

In fact this is probably what I'm looking for - any of you guys any experience of them? or where to buy?
Would it inflate a motor bike tyre?

Not so sure about that man, I've plugged many a puncture with strings with no issues

I wouldn't trust them, ok in the car but not on the bike, check your insurance too as improper repairs can cause problems there too.

Skill Magill

Depends on the puncture i suppose, and the way you drive, if you're pottering around town they're fine.

The lezyne pumps are brilliant. If you end up getting a bicycle type mini pump, they are the ones to get. (I have the lezyne pressure drive)

^^
I can get one one amazon for about €50, I might go for it.

I disagree. I have been plugging motorcycle tyres for over 25 years without problems. In 1996 I rode a Ducati Superbike around the TT course on Mad Sunday with 2 plugs in the rear tyre, at very high speeds.
OP, One CO2 canister will inflate a 150 ish tyre enough to allow you ride slowly to the nearest garage.

Same here, I've been plugging tyres for just as long.

OP in regards to a mini pump I don't have any experience of using one on my motorbike in an emergency but I do recommend a floor pump with a gauge for any motorcyclist.

I use the Halford one, I've calibrated the gauge from my digital gauge and its accurate.. Great bit of kit or the cyclist and biker.

My point being, in an emergency at the side of the road, you've fixed the puncture, and you need to inflate the tyre, now don't forget you're miles away from any assistance, what pump under your saddle will get you out, to get you off the the side of the road and back civilisation?

They do, but if all you need is to reinfllate your tyre, having a little pump on you
would save you a lot of time. (also giving them directions to an unfamiliar place could prove a tad problematic )
The zefal hpx looks a bit long though

It is full length, though there are short versions. I suggested it as I said, if you value your time.
For what you want gas canisters would be best. Might take 5 or 6, and you'd want to verify what co2 does at higher temperature in tyres.

Skill Magill

I hear ye, probably use them to get me to a petrol station, and put proper air in there.
