“Hardy” Scrambler: Yamaha SR150 by Zoth Moto

Yamaha SR150 Scrambler

The Yamaha SR150 is known in Taiwan as a “white plate” motorcycle, a bike free of the high taxes and twice yearly safety inspections (!!) required on larger motorcycles — restrictions that can make it tougher to run a workshop building hand-crafted custom motorcycles. Fortunately, there are builders up to the challenge, such as 24 year-old Zoth Huang, who began rebuilding and selling vintage motorcycles to earn money through college. Two years ago, he opened his own workshop, Zoth Moto:

“We offer hospitality for everybody coming our shop, they can chat, can DIY their motor, and we’re always drinking together on Friday night. We want to build a space that every customer enjoys being here.”

Motorcycles have a history of bringing hearts together, and so it was for Zoth and his girlfriend, Chrissy (@yourlordchrissy), who owns the 2003 Yamaha SR150 scrambler you see here:

“This motor belongs to my girlfriend, Chrissy. Last year she had an accident and her SR150 was crashed, then she came to my motor shop and told me that she wanted to rebuild it. And because of this accident, we met each other.”

Chrissy needed a bike for daily commuting, but she also likes to go exploring on the weekend, so Zoth wanted to build a machine that would combine the convenience of a street bike with the “wildness” of a scrambler. The result is “Hardy” — a lightweight scrambler that echoes the vintage Yamaha enduros of yore.

Below, we get the full story on the build.

• Please tell us a bit about yourself, your history with motorcycles, and your workshop.

My name is Zoth Huang, 24 years old, come from Taiwan. When I was in college, I majored in department of restaurant institutional management. But I have strong passion in motorcycles, so I started to learn how to build hand-crafted motorcycles at a motor shop from the time I was 19 years old (a freshman). At first, I rebuilt and fixed vintage motorcycles and sold them for earning my allowance, then about two years later I officially crossed the divide to hand-crafted motorcycles. Therefore, the brand Zoth Moto was born in 2018.

The environment for hand-crafted motorcycles in Taiwan is tough, and the laws for handmade motorcycles in Taiwan aren’t friendly. Therefore, we have the harder way in this career.

About our workshop, we have three guys, one as an apprentice, one as me, Zoth, and my girlfriend Chrissy. In our leisure time, we offer hospitality for everybody coming our shop, they can chat, can DIY their motor, and we’re always drinking together on every Friday night. We want to build a space that every customer enjoys being here.

This motor belongs to my girlfriend, Chrissy. Last year she had an accident thus her SR150 was crashed, then she came to my motor shop and told me that she wanted to rebuild it.

• What was the design concept and what influenced the build?

The main concept is to design a motorcycle that can do commuting and enduring. The SR150 is the motorcycle that has a beautiful big engine and good “cradle type” frame, but the size and weight are too heavy for Chrissy (about 160cm height), so we wanted to build a lightweight and smaller proportion of this motor, so that it would be suitable for Chrissy to ride. As a matter of fact, all concept is around this girl.

    Nice Build ,but rear fender /shield needed .

  2. Perfectly proportioned! It captures the graceful early 1970s lines of old Yams. The Triumph style tail light is cleaner than the originals.
