Fork springs

These progressive springs have transformed the bikes handling.It no longer suffers from patter and absorbs the bumps really well so I no longer have to brace on bumpy roads.Best mod yet.

Best bang for the buck mod on a t120

Just put these onto my t120. Installation was straightforward. Wasn’t sure of what to expect in spite of all the good reviews. After trying them, all I’ve gotta say is they should’ve been what was installed from the factory.

Smooth ride

Got my progressive springs last week. Mounted them and took a ride near my hometown. A ride I have made several times before on summer evenings. There are a lot of uneven brick roads. I was very surprised about the smoothness of the ride. Smal bumps were taken with much more ease. The bike also responds nicer on steering action, even though my front tire isn t that good. (needs replacement when temperature is above 16 C) All in all a very affordable upgrade of my triumph T 120. The costs for dutch VAT and customs were eu 28,40, which is hardly more than before Brexit. The overall feeling is firm but not hard. The road contact feels more direct.
I am very pleased with my purchase and can recommend it to every T 120 owner. Fine TEC product

Big improvement over original

My observations as follows:
Easy fit - good instructions.
Noticeably improved front end over stock.
Only done about 200 miles on them, but so far, very pleased.

very nice

I ran 500km after the replacement, but I am very satisfied with the light movement in the beginning and the stickiness in the second half.
Thank you very much.
