Progressive fork springs

Fitted to my bonneville they give a less jarring feel to sudden bumps. Which is what l was looking for so it’s a thumbs up from me.

Great service

I must admit that I ordered the wrong springs for my cast wheel bonneville , but this was swiftly rectified thanks to the great service from Tech Parts. A big thankyou to them. I have not had the opportunity to have a long ride yet but a quick run around the village showed that there was a massive improvement over the stock springs. I fully expect to enjoy a much more comfortable ride in future. Once again thank you Tech Parts for the great service.

Triumph T100 - front and rear suspension

I ordered front and rear replacement suspension for my T100. Arrived in good time and easy to fit. They have made a massive difference especially the replacement progressive front springs. Cheers Paul

Definite improvement

Dead easy to change out with the stock springs and noticed the improvement on the first ride: more positive on the bends and definitely smoother, particularly over ridges and ripply bumps. Well worth doing!

Noticeable improvement.

Went from a Thruxton R to an older T100.Needless to say,it was a bit of a shock(pun intended). These progressive springs has noticeably improved the front.Haven't got round to fitting the rears yet,but expecting further improvements.Always good value for money from these guys.Keep it up👍

Recommended Upgrade

Having installed TEC adjustable rear shocks upgraded front forks with Progressive Fork Springs Kit based on positive reviews - Very straight forward fitting, (good instructions provided) all done within 30 minutes - Not disappointed and noticeable difference from the off! Provides a far smoother ride and now handles bumps in road with ease with significant reduction in jolts and good resistance in forks on braking - Triumph Bonneville Spirit 2015 - 4K miles now on clock! A great value upgrade and worth investing in!

Well worth it

Good quality product. I'd read other reviews here and there and these really do the job, so much so I'm considering the rear shocks now. Easy to fit on a 2015 T100, 30 mins tops.

Progressive fork springs

These things are the best £60 I've ever spent on my T100. Unbelievably good. They reduce fork dive greatly which in turn improves braking, no crashing and banging over bumps anymore and I can't even feel small imperfections in the road surface anymore. If you haven't got these on your bike, get some. Only takes half an hour to fit them too. Brilliant!

Seem Good Value - Apart from Black Friday event even cheaper

Reading numerous reviews/forums many owners upgrade there suspension. Looking at the reviews various brands were mentioned and "tec" being one of them was noted for good value. As the bike is 12yrs old top brand/spec items were ruled out as value of bike low; so went for these. Having only just fitted 21/11/20 can not yet comment on improved ride quality (lockdown), but should be an improvement over originals.

Cuts the diving by about 50%. Makes the front suspension a bit stiffer which it needs and stops the diving under all breaking. The standard springs are too soft. Coupled with the rear springs and its a much nicer ride.

Just fitted a set of these in place of the stock springs. Very easy DIY job. Made a fantastic difference to the ride, really impressed given the cost. This in addition to a set of rear Hagon shocks have made a great improvement to the bikes handling.

Ordered, delivered and fitted springs within 24hrs ! Noticeable front end improvement .

Theses springs are a must for anyone running stock front springs in a Bonneville. I ordered the springs on a Wednesday lunch time and they arrived the very next day, all this despite TEC's site saying they were closed for their annual holiday's. The springs took less than an hour to fit, and the improvement was apparent immediately the first time I rode after fitting. Without doubt the best £55 you'll ever spend on your Bonneville.

Bought last year but only gotten around to putting pen to paper! A must buy for a bonnie. Instant improvement over stock springs. Best paired with new rear shocks to really get the full effect. Excellent product again from TEC.
