Hi. Might seem a daft question but which way round do the progressive fork springs go? (Bullet 65)The Hagon site says "tight coils to the top" Can't see anything on this site and no instructions with the springs. I doubt it would make much difference, what do you think?

hi Bob my advise for what its worth is do as Mr Hagon says i,m sure he knows a thing or two about these matters atb Paul.

agreed tight to the top.

Hi guys----------- It's all to do with "Unsprung weight" etc.......For our type of "cooking" bikes it doesn't make any difference, but for the racing fraternity every bit counts and as the closer wound coils are effectively a greater MASS than the same length of wider wound ones then the lighter end goes nearest the moving part of the forks/shocks etc.......Same idea applies to railways, HGV etc.....Unsprung Weight needs to be kept to a minimum when designing...............

I had to cut about a 100mm of a pair of springs yesterday on a bobber that had extended forks fitted.He turned up with new tubes but no new springs. I know he got home ok, but I didn't ask how well it handled lol

When I needed to know the answer to this question I asked a number of spring manufactures – some said tight coils to the top, some said tight coils to the bottom. The truth is that on a Bullet it makes no difference ay all to the ride, steering, or handling. But makes sense to fit them both the same way round, whichever way round that happens to be.
