Here is a table with the measurements of the space available for the rim and its tire on the different G-craft arms for Honda Monkey and replicas.
These tables allow you to choose the correct arm length depending on the tire and rim you want to place.
For example :
a Michelin S1 Tire 130/70 x 10 mounted on a 5.5 wide rim = 422mm in diameter, i.e. 211mm in radius. With a bi-shock absorber arm you need at least a Stock Look with reinforcement + 4cm with 214mm available. Or a minimum of 16cm in mono-shock absorber, because 220mm is available. Please note that the Stock look + 2cm or the Triple square + 4cm could be suitable with 210mm available but you will not be able to put the wheel to full tensioners

All measurements were taken with the wheel axle at the minimum.
First case: the arms with two shock absorbers. The measurement is taken from the wheel axle to the main brace of the arm as in this illustration.

| Swingarm Length | Section STD | Triple square | Triple square Mini | Stock look | Stock look + braced |
|---|---|---|---|---|---|
| -2cm | 185mm | – | 160mm | – | – |
| 0cm | 205mm | 190mm | 180mm | 190mm | – |
| +2cm | – | – | 200mm | 210mm | – |
| +4cm | 225mm | 210mm | 220mm | 230mm | 214mm |
| +6cm | 245mm | 230mm | 230mm | 250mm | 234mm |
| +8cm | – | – | 250mm | – | – |
| +10cm | 265mm | 270mm | 270mm | 274mm | – |
| +16cm | 325mm | 330mm | 330mm | 334mm | – |
| +20cm | 365mm | 370mm | 370mm | – | – |
Second case : mono shock absorber, in this case the support is central and takes up significantly more space. It is therefore important to choose the right length according to the wheel you want to place there.

| Longueur du bras | Section STD | Triple Square | Triple Square Mini |
|---|---|---|---|
| +10cm | 160mm | 160mm | – |
| +12cm | 180mm | 180mm | 180mm |
| +16cm | 220mm | 220mm | 220mm |
| +20cm | 260mm | 260mm | 260mm |
