Honda Wave i125: Custom Building a Sidecar in Thailand

Thailand is very liberal regarding the rules regarding passengers on motorbikes. Take, for example, a Honda Wave i125 with a custom-built sidecar in Thailand, which we will look into in this blog.

But before that, regarding rules, one might say that the authorities are not just quite so strict about enforcing those. 

However, you can install a child seat on a motorbike and drive quite “safely” by any standards with a kid on a bike. The issues start, though, once the family gets bigger.


Google the Keywords

Ever since I have always been into motorcycling in everything I do, but when it came the time that we had a couple of growing boys, a solution had to be found.  And a custom-built sidecar in Thailand was the answer! A Double Seater. 

I googled countless websites, compared solutions, browsed chat rooms, and reviewed dozens of products. I became an expert on the advantages and disadvantages of the whole concept. Also, I studied the technical elements like weight distribution, form factor, how strong the motorbike has to be, how many CC the power plant should be far enough to, etc.

I was conscious not to forget how it should look the whole time.


A Real Sidecar for Honda Wave i125!

I discovered that there is a fantastic variety of sidecars available in Thailand. It ranges from the classic luggage sidecars (just a metal frame with wooden boards on the floor) to luxury cabins with velvet cushion interiors…

But I didn't want something like that. My dream was to have a real sidecar with the perfect combination of utility and style.


Thinking about Sidecar Importation

I looked into some offerings from all the big sidecar companies like EZS, Liberty, Dauntless, California, Champion, and many more. I checked all the stats like dimensions, weight, material, and hardware. 

Also, in the meantime, I thought about buying and importing it. However, this idea quickly went nowhere, as it essentially failed in three ways:

  • import sidecars are designed for larger motorcycles
  • attachment fittings for my motorcycle would have to be made in Thailand
  • the murky world of customs regulations and import taxes in Thailand

And ultimately, it is, of course, also a question of price. An imported sidecar would cost at least 500,000 THB. That’s ten times more than the motorbike price and 20 times the custom solution price I eventually went with locally in Thailand.


Never Stop Searching

Searching for a sidecar builder in Thailand was extremely difficult, and maybe I started it wrong. Contacts with companies building TukTuks failed; building sidecars is just not what they do. Those who build the metal luggage sidecar types have no technology for fiberglass body parts. In addition, a pure metal variant that would look nice would be too heavy for the Honda Wave i125.

Finally, I found help at a car repair shop that also repairs big trucks. They had experience with fiberglass through all the modern bumper repairs they regularly perform. They were familiar with stable structures for weight and had everything to custom-build anything. You can also rent motorbikes here! The project dragged on for months. In the end, it was conveniently finished right on my 38th birthday.


One of My Best Birthdays

It felt good to finally have the sidecar I need for my Honda Wave i125. It felt like a lovely birthday present for me. A proper motorbike restoration with added sidecar bonus - I must say!

However, it turned out that using it is an entry into an entirely different world! I learned that a custom build sidecar in Thailand drives very differently than a motorbike. The driving characteristics were excellent but unusual. When turning left, the motorbike tilts to the left, but the sidecar pulls you to the right – this can cause you to fishtail like a car. 

Turning the other way is even more tricky because the sidecar will lift off the road if you go too fast. Some guys I know caught some air underneath when that happened, and the whole thing tumped over! But you get used to it after a few kilometers, or maybe a few dozen kilometers. And in a week or so, all these quirks become second nature to the ride.


The Pros and Cons 

The kids love the custom build sidecar! Suddenly, my kids had plenty of space to take everything with them everywhere we went. We could go grocery shopping just like with the car, and even relatively big things were easily transported. 

Many people don’t have one say that a custom build sidecar in Thailand combines the downsides of a motorbike and a car. An example is when you get wet in the rain, and that thing isn’t small enough to run between the cars in city traffic. 

Well, yes, maybe that’s mostly right. However, Thailand generally has excellent and stable weather conditions, and lane-splitting cars are not a big deal since the traffic in Pattaya is not as heavy as in Krung Thep Maha Nakhon (Bangkok)

So actually, you still have advantages over cars - especially when it comes to parking spaces. A custom build sidecar in Thailand is still as short as a motorbike, so you can park it the same as a motorbike. You need the space that, generally, 2 or 3 motorbikes would take.

Our accessory top box also had a lockable space, and we use it all the time. I think it all comes down to the question of whether you like motorbikes or not.


Another Problem Arises

All this about our new sidecar was great, but we were not done yet. One little thing made this project a true winner besides all the other cool stuff. Since we live close to the beach, we got a small fiberglass boat. 

We had a car, but it would be terrible to pull this small boat with a car, and it’s too big to fit in the back of our pickup…


We Solved It!

We tow it with the sidecar! We added a simple custom-built metal fitting to the top case mount and installed a trailer hitch. As you can see in the pictures, it was a lot of fun, and all the neighbor kids loved it, joining us on many trips to the beach with our sidecar and boat.

So then, with a family, a custom build sidecar in Thailand is a good solution for all-around motorbike travel. We have done over 40 thousand kilometers with the sidecar in 8 years. And the motorbike has never had any problems with the heavy load.

We enjoy visiting all the beautiful places around Pattaya and have never felt held back by running around with the sidecar. 

I never regret doing it. Life is the sum of all our choices, and happiness is not by chance but by choice. So, I would build it again. 

So, until next time... Rumble on!
