Im looking at buying a Vertigo vertical DL 2018 300cc, Am I doing the right thing, looks mint condition & states it as only been used in local trials. Do they have a dry & wet switch to change the mapping? People say they can eat plugs, & can have electrical issues, Im no trial rider but my two sons are,, Beta 300 4 stroke, GasGas 280 2 stroke, and want to do local trials. I did win a trials once,, G Limber champion back in 1980 but now 59 might not be as easy! please any advice would be greatly appreciated. if you have had an 2018 model or been around them that would be so helpfull.
