World Record Attempt

Posted by on January 26, 2013

Hi Folks..
Sorry its been ages since I updated the blog!! I have been putting up regular updates on facebook and daily updates recently.

I have a few tales to tell about Peru and Bolivia, but I will have to back track to update you on that.

What I want to do know is fill you in on my world record altitude attempt on the Honda.

How high can a Honda cub go before it just can’t climb any further or with just won’t run? I became interested in this when I reached 5000m on the El Burrito in Peru. It was freezing cold, snowing and icey but yet the bike was still running and could have kept climbing if the grades weren’t too steep.

I started doing some research and didn’t find any record set by a Honda Cub and I found out the World Record for a motorcycle was broken last year in Chile. It was set by a very well resourced international team using 550cc Husaberg with a high compression engine. They reached 6,331m. They had to cross a glacier to reach this height. You can read all about that at, it was quite grueling, they had to use ropes to pull the bike up some sections!

The record was set In Ojos de Salado, around 150 km north east of Copiapó in Chile. Ojos de Salado is the highest active volcano in South America and its sides have a relatively gentle gradient.

So I have chosen this area to make my attempt. The highest motorable road in the world is in Tibet at 5,565m. My aim is to beat this and set a new altitude record for a Honda Cub.

Any reader of this will be aware of the Honda Cub’s status in the world. It is the most iconic motorcycle in the world and holds the record for the most produced motorcycle (and vehicle) of all time having sold in excess of 60 million motorcycles! So a record should exist for it. I have applied to Guinness World Records to create a new category for the highest altitude Honda Cub.

Altitude and Risks

There are many risks associated with undertaking this. Firstly the effect of altitude on the human body. If proper acclimatisation is not carried out then there is risk of experiencing altitude sickness which can become serious plus there are risks of developing pulmonary edemas.
The reduced level of oxygen over 3000m means that ever action carried out above these height can be very physically taxing on the body. Any time spent over 5200m starts to weaken the body. Nobody lives above 5250m around the world.

To try an give us a good chance of making this we will be spending between two to 3 nights above 3700m.

Secondly weather conditions and the cold is going to be an issue. At these altitudes; any rain or snow and  things can very cold very quickly.

Thirdly, actually keeping the bike running at this altitude maybe difficult. Fuel needs oxygen to burn above 5000m the air density is around 50% of sea level air density. Therefore the bike will tend to run rich as all the fuel being sucked into the engine will not be combusted thus the bike being severely down on power and it simply might not fire up up much over 5000m.

Team Honda Vs The World
To undertake this challenge I have assembled a crack team of international experts, all experts in their particular field. My brother Gavin Dillon and Gordon Jackson. Gavin’s is in charge of opening tight jars and tying ropes. Gordon is in charge of eating stuff and lifting heavy things. I’m in charge of balancing pineapples on my head and making the bike go.

But seriously, Gavin is a trained crane operator and rigger and Gordon is a trained firefighter and first responder, he is also a stripper (though I’m not sure how that skill might come in useful on the side of the volcano).

I have been busy the last few days applying for permits to climb the mountain, I have put a lot of thought into the safety aspects of this as obviously it will be a risky undertaking. I will have my SPOT Connect GPS messanger with me also, I can send SOS and Assist Messages from this device. The messages are received by an international operations room who co-ordinate a rescue attempt with local emergency services.

The bike.
I have changed the front sprocket from and 15 tooth to a 13 tooth sprocket. I have also changed the rear sprocket from a 39 tooth to a 45 tooth. This should give me some great climbing ability. I will not touch the carb apart form opening out the air screw. The needle is already in its lowest position. I have got a smaller main jet which I may use if i cant get the bike going at high altitude.

I have also taken the clutch apart and cleaned the clutch plates to make sure they have good binding. As a trial run I stripped the bike down to the form it will be used on the mountain and relocated the back box. This will be put back to the old configuration for the ride out there to carry all the equipment and supplies and then put into ‘mountain mode’ again at Camp Murray.

We have no support vehicle so we have to carry everything with us on the bikes. Enough food, water and gas for 6 days, plus our camping and cooking gear and spare clothes.

I’ve managed to get my hands on 2 GPS’s a Garmin eTrex 20 and a Garmin Colorado 400t. Thanks Omar and our buddy Darren from Darren&Eric otherwise know as Derik.

The Plan

Day 1-2- Copiapo to Luguna Santa Rosa  – Depart on Monday 28th January.
We will leave Copiapo and drive 120 km to Laugna Santa Rosa (3700m above sea level). We will stay there over night to acclimatise, do a spot of exploring and maybe some fishing. Here we will check over our gear and make any modifications to the bike. The bike will be stripped of everything unnecessary to lighten the load.

Day 2-3 We will make our move to Camp Murray. Camp Murray is located at 4500m. We will over night there and prepare for a difficult day the next day

Day 3-5 Ojos de Salado
These 2 days will be spent on the mountain side trying to bring the bike as high as it can go. Depending on our progress the bike may have to be abandoned on the side of the mountain over night and another crack made at it the next day.

Day 5-6
Time to make our way down the mountain. Hopefully sucessful with a new World Record under our belts!!. We may over night again at Laguna Santa Rosa on the way back.


You can keep and eye on our progress on the the “Where’s Seán?” button on the website. The SPOT device will track us a update the map every time a location is sent I will also be able to post short messages on Facebook from SPOT GPS devise.. how cool is that eh?

Hopefully the  next time I write here we’ll have be the holder of a new World Record for this recording breaking bike!!!
