Suspension Tuning Tips

Condition: 

Possible Solutions:

Not  using  full  travel,  feels  harsh,  poor 

cornering traction

Lower  air  pressure;  softer  compression 

damping;  lighter negative spring;  damper 

revalve

Bottoms  out,  soft  throughout  travel, 

excessive sag

Increase air pressure or stiffer coil springs; 

firmer compression damping;  revalve 

Harsh  over  large  bumps,  but  good  over 

small ones

Softer  compression  damping;  lower  air 

pressure or softer coil springs; revalve 

Harsh  over  small  bumps  but  uses  full 

travel

Lower air pressure or softer coil springs; 

softer  compression  damping;  reduce 

spring preload; decrease bump threshold; 

firmer negative spring;  revalve

Fork dives under braking 

ncrease air pressure or stiffer coil springs; 

firmer  compression  damping;  increase 

SPV  pressure;  decrease  SPV  volume; 

revlave

Harsh  on  repeated  bumps,  packs  down, 

feels  like  less  travel,  poor  traction  in 

corners

Faster  rebound  damping;  increase  air 

pressure or stiffer coil springs

Rebounds  too  quickly  after  bumps, poor 

traction in corners

Slower  rebound  damping;  lower  air 

pressure or softer coil springs

Fork tops out harshly 

Lower air pressure; slower rebound; firmer 

negative spring; bearing reset
