2.3 CONNECTING THE HARNESS

The IKUMA 2 risers are colour-coded.  
- Right: green
- Left: red 

This colour-coding makes it easier to connect the wing to the correct 
side and helps prevent pre-flight errors.

Correctly connect the risers to the attachment points so that the risers 
and lines are correctly ordered and free of twists. Check that the IKS or 
carabiners are properly fastened and securely locked.

PLEASE NOTE! The IKUMA 2 features risers of different lengths. Size 
22 uses risers of unequal lengths. In all other models the risers are 
equal length and interchangeable - but NOT on the size 22.

4 TYPE OF HARNESS

The IKUMA 2 can be flown with all current harness types, provided they 
can be adjusted to the settings stipulated in the certification.
Please note that these proscribed settings vary for each size and within 
each size if flown at the upper or lower end of the weight-range.

Distance between the risers:

Size 22 - 40/44 cm
Size 24 - 40/44 cm
Size 26 - 44/48 cm 
Size 28 - 44/48 cm
Size 30 - 48 cm 

Distance between the harness/risers: 

Size 22 - 42/44 cm 
Size 24 - 44/44 cm 
Size 26 - 46/43 cm 
Size 28 - 44/44 cm 
Size 30 - 43/44 cm

Care should be taken with the chest strap setting, as the distance of the 
chest strap setting will affect the handling of the glider. If the chest strap is 
too wide, it allows greater feedback but this carries the risk of affecting the 
stability of the wing.  
If the chest strap is set too tightly, the wing feels more solid, but there is a 
loss of feedback and a risk of twisting in the case of a violent asymmetric 
collapse.

See the certification report.

2.5 SPEED-BAR

The speed-bar is a means of temporary acceleration by changing the 
flow over the profile. The speed system comes pre-installed on the risers 
and is not modifiable as it conforms to the measurements and limits 
stipulated in its certification.  

The IKUMA 2 includes a speed system with maximum travel depending 
on its size (see below).
The speed system is engaged when the pilot pushes the speed-bar - not 
included as standard with this glider model - with their feet (see 2.5.1:  
Speed system assembly)

The speed system uses an action/reaction system. Released, the speed-
bar is set to neutral. When the bar is pushed using the feet, the wing 
accelerates. The speed can be regulated by varying the pressure on the 
bar. Once the pressure on the bar is released, the speed system returns
