If you're building out a Sur-Ron or Talaria, one of the cheapest ways to shave weight is swapping stock steel hardware for titanium. Here's the actual difference it makes.
Weight Savings: Titanium vs Steel
A typical steel M8 bolt weighs roughly 15-20% more than an equivalent grade-5 titanium bolt of the same size. On a single bolt that's negligible. Across a full hardware set — stem bolts, subframe bolts, controller mounts, brake lever hardware — the savings add up to several hundred grams without touching a single structural component.
Does Titanium Hold Up to Real Riding?
Grade-5 titanium (Ti-6Al-4V) matches or exceeds the tensile strength of most stock steel fasteners used on Sur-Ron and Talaria platforms. It's more corrosion-resistant than steel, which matters if you ride in wet conditions or near salted roads. The tradeoff is cost, not durability — titanium hardware costs more per bolt, but for a hobbyist or racer who cares about power-to-weight, it's a straightforward upgrade.
Where to Start
The highest-leverage swaps are the ones where you're already handling the bolt anyway during a service or upgrade: stem bolts, subframe bolts, and brake lever hardware. These are also the parts most likely to strip or corrode on stock steel over time, so it's a weight save and a reliability upgrade in one swap.
