T500 fork springs

Post by Willsy69 »

Anyone know if any other fork springs (triumph / BSA etc) will fit the T500 front forks?
I’m having trouble locating any Suzuki ones.
Cheers

The T350/T500 external fork springs are overstressed according to the online spring analysis tools. So they end up sagging.

Had the same problem with an early T350. An early topic about the problem.

Later decided on a new spring that worked out quite well.

Remember reading about someone having springs made that were stiffer than stock T500 springs. Worked out badly & they switched back to stock.

Given how short the T350/T500 springs are, likely the best solution is softer + longer springs.
The Triumph springs I found went in the other direction & likely ride like crap.

Depending on your weight & needs, you might need a little more spring that what I used on the T350.
Plus there might be better options available in the UK.
