A shopper asked: Hi, I have a 2009 Triumph Thruxton and want to upgrade my suspension but need help deciding which Progressive 412 shocks to get.
I weigh 105KG's so was going to get the Heavy Duty model but not certain which length I should get 12.5",13" or 13.5"?

Can you help.

Marvin J: Thruxton stock shocks are roughly 14.37" long. So if you wan't to keep stock height, look for the Progressive 412 Thruxton specific ones (they are 14.25")

If you are wanting to lower the Thruxton then get either the 13.5 or 13. You will want to raise the forks a bit so you can even out the bike.

At your weight of 105Kg, you will want the Heavy Duty one's.
