Thank you for viewing. This is a front carrier for vintage Vespa vehicles. It can be installed on all vintage vehicles such as 50/100/ET3/STD/SUPER/SPRINT/GS/etc... Overall size: Width approx. 32cm, Height approx. 38cm Rubber is attached to the back of the upper hook that hooks onto the leg shield. The included mounting金具 (metal fittings) hook onto the center nose (under the horn). The spring is strong and excellent for holding magazines, skateboards, etc.! If you think the spring is too strong, it's best to pinch and remove the spring from where it's hooked in the first place. In that case, you can secure the opening and closing part with Velcro or tie it with rubber. Or, you can leave it folded down (open). You may need to bend the included metal fittings slightly for installation. ☆ PX series cannot be installed in principle because the nose part is plastic (metal fittings cannot be used) ★ For PX series or those who frequently remove it, you can use rubber etc. to go around it without using metal fittings, or fix it to the left and right (leg shield). We use rubber fixing on the left and right (image 3), but this is not included. We do not negotiate discounts. Please understand. m(_ _)m
