The Ultimate Guide to Motorcycle Frame Tubing: DOM vs. Seam Welded
Introduction
When it comes to building a custom motorcycle frame, choosing the right tubing is crucial. The most common options are DOM (Drawn Over Mandrel) tubing and seam welded tubing. Both have their own advantages and disadvantages, so it's important to understand the differences before making a decision.
DOM Tubing
DOM tubing is created by drawing a steel tube over a mandrel, which gives it a consistent thickness and a smooth, seamless finish. This makes it ideal for applications where strength and precision are critical, such as in motorcycle frames. DOM tubing is also relatively easy to weld, making it a good choice for do-it-yourself frame builders.
Advantages
- Strong and durable
- Consistent thickness
- Smooth, seamless finish
- Easy to weld
Disadvantages
- More expensive than seam welded tubing
- Not as readily available
Seam Welded Tubing
Seam welded tubing is created by rolling a sheet of steel into a tube and then welding the seam together. This type of tubing is typically less expensive than DOM tubing, and it is also more readily available. However, seam welded tubing is not as strong as DOM tubing, and it can be more difficult to weld.
Advantages
- Less expensive than DOM tubing
- More readily available
Disadvantages
- Not as strong as DOM tubing
- More difficult to weld
Conclusion
When choosing between DOM tubing and seam welded tubing for your motorcycle frame build, it is important to consider the strength, weight, and cost of each option. DOM tubing is the stronger and more durable option, but it is also more expensive and not as readily available. Seam welded tubing is less expensive and more readily available, but it is not as strong as DOM tubing. Ultimately, the best decision for you will depend on your specific needs and budget.
