    The R18 sidecar thread

    Wonderful ride out with some members of the classic vehicle club. With ideal weather form one village Fiesta on the north side of the mountain range to another village fiesta on the south side to another on the north side again :love:

    About the tire pressure. The front tire of a sidecar rig is the critical one. Higher pressure is less understeer and vv. As such higher pressure results in more direct steering response. Less pressure, thus more drift angle, reduces the sidecar wobble and vv. This does not mean more amplitude...

    The inner tube was in Friday but I had other obligations so went at opening hour this morning. Took the wheel out, the mechanic took the tire off. The inner tube had a 1 cm slit. Nothing in the tire. Weird. The 120/70 inner tube ís a bit small for the 4.00 tire. The new extra heavy duty...

    Thanks for sharing @R2K Looks much like yours. Not my first choice of color though. Over here it is the Correos (Post) color :oops: Me, I am planning to go hands on tomorrow morning with the new inner tube. Want to get to the root cause. Miss the rig: It is rather in my face in the apartment...

    Most likely not perfectly mounted inner tube with possible for this tire to low OEM spec pressure. There is a rip at the valve in the inner tube.

    wow that was scary.... Nice weather... dûh... so out with the R18. On a réaly tricky section, narrow with tight blind corners where nigh everyone goes though too fast and the berms look like a bumper plastic cemetery, had a blow out of the front tire. One of those moments you are saved by...

    and... relief... received the 5 l. metal German made thus réal Jerry-can. The autonomy is nothing much riding solo and it goes down come 20% with the rig. Even though the fuel light pops up plenty early it does give range anxiety.

    The tub only allows for upper body movement and just a grab rail in front of the passenger. Still makes a notable difference. Not so much as me monkeying but still fun as it is coordinated team action. A crucial aspect of cornering with a rig is the traction of the front tire. Because of the...

    Yesterday great day riding Vespa the three of us. Even a dozen kms dirt roads because the local road was being resurfaced. Was very proud of my son. So today was earmarked for the R18 rig. Was going out for lunch a few hours up the road. Son sent message that he wanted to come along passenger...

    Thanks. I was wondering. Yes, living here makes me forget a bit about weather.

    Yesterday, Sunday, morning and an elderly neighbor had expressed the wish to for ´churros with chocolate´ in the village up the road for her upcoming birth day. Loaded up in a car with her husband. Friend of mine in front on a Vespa and me behind with the R18 rig escorting. She was chuffed to...

    ALL sidecar rigs are prone to low speed front wheel wobble. It is rather gentle, occurs at a low speed range and it easy to mitigate. The cause is the toe in. Imagine the line of the wheels of the trcktor and that of the sidecar wheel. It is easy to envisage that the distance gets closer...

    Today took the rig out for an easy spin. Well, as for as the R18 can ever be easy here in de mountains. A rain shower again. In a normal summer is does not rain, period. This year we have the odd local showers. For the past 4-5 weeks basically once a day, Just a few minutes but big drops. Most...
