Hello Mark, Good news, yes the ST forks fit and without any mods. I also have an old (but beautiful!) 93 Trident which has the Speed Triple forks fitted along with the bigger brakes and 4 pot calipers. the Forks have been dropped through the top yoke (triple tree's for our American cousins) by about half inch to quicken the steering.I would like to upgrade the front forks on my 1993 Trident and fancy a set from a 900cc Speed Triple as they have some adjustment. Will these fit straight on and accept Trident wheel, discs, calipers, bars without any mods??
