Stainless Steel Engine Mount Bolts (Motor Mounting Screws) – Hyosung GT125 GT250

Description

Upgrade your old, rusty engine mount bolts with this premium set of stainless steel replacements, custom-made in the UK. These are the main bolts that secure your engine to the bike’s chassis/frame — a critical area you don’t want to leave to chance.

✅ What’s included:

• 3x high-quality stainless steel engine bolts

• 3x stainless steel matching nuts
  (Fits like OEM, but won’t rust like them!)

🔧 Why upgrade?
The original Hyosung bolts often corrode badly or get damaged during engine removal. These stainless replacements are made to outlast the bike — no Chinese knock-offs here. Our local UK bolt maker supplies these to spec, ensuring durability and strength for critical load-bearing points.

🛑 Your engine can weigh over 30% of your bike’s total weight, so do not gamble on cheap hardware. This is a structural, safety-critical part.
