AT Suspension upgrading options ?

Hi Forum. Considering an AT. I've heard the front spring of shock of this bike is sized for about 165lbs. I'm 200lbs without any gear. Any suspension upgrade options ?

I dont think there are any issues with the front end at 100kg, wind on some pre-load. Depends on what the intended use is but dont know why you would spend money on that from the get go.

I'm 200 lbs as well. All I've had to do was put some preload in the rear shock and it rides like a dream.

I think Wilbers have a contribution also.

The springs handle the mass (weight) of bike and rider. Bike is the largest part at say 540lb; with 160lb rider total 700lb. With 200lb rider total 740lb = 6% total difference despite the rider himself being 25% heavier.
Just set the rider sag with the preload adjusters. 25% of front travel and 33% of rear. Only consider stiffer springs if you can't get proper sag setting with preload maxed out.

Agree with black99s, don't buy anything until you try adjusting the suspension preload as he suggests. I am heavier than you but can get this bike to ride pretty nicely, solo or two up. I find the rear needs loads of extra preload compared to the front. Two up with lots of luggage would be a problem for me though, I would have to invest in the rear at least.

250X7 (first bike 17 years old, T-Boned it in 3 weeks), CB250K4 (needed wheels), CB350K4 (last wheels needed replacing, ran engine without oil after rebuild, DOH!), T500 (didnt handle, didn't care, 2-stroke smoke - EPIC!), 883 Sportster (oh dear, mistake), 1340 Lowrider Covertible (stolen before a year old), Daytona 1200 (heavy, 147BHP mad lump), DR350 (reliable small thumper), CRF1000 (love it)

Why 25%/35% I've not spotted that recommended on any suspension tuning sites (I'm trying to get aftermarket suspension on an NC750X right)

I replaced fork and shock springs with Hyperpro primarily for the 20 mm increase in height. I planned on changing fork oil as usually Honda's looks like whale mucous but factory fork oil was red and high quality. Changed out with Hyperpro's 15 wt replacement. More adjustment for my weight, more than half of pre-load remaining for heavier loads.

I have ordered Hyperpro front and rear kit also, from touratech.

My reasoning is that the rear suspension on the road, is for me at virtually full preload. No extra for wife or luggage and we have a trip planned. It feels awful with a pillion.

If I'm doing the rear, I might as well upgrade the front to even/balance things up.

I expect it to be a good upgrade and be noticeable, although as a solo bike the suspension is fine on road.
