‘Even an en­gine this solid can only take so much’

Motorcycle News (UK) - - BUYING & SELLING -

“The prob­lems with all used 125s are down to the pre­vi­ous owner. If you get a sym­pa­thetic owner, the bikes are strong, but how many me­chan­i­callysym­pa­thetic 17-yearolds are out there? I’ve seen so many 125s that have come in for a ser­vice with vir­tu­ally no oil in their en­gines and the owner still ar­rived at 70mph with the mo­tor on its rev lim­iter!

“When view­ing a used bike, look for signs that the pre­vi­ous owner has a de­gree of me­chan­i­cal abil­ity. Ask them how you check the en­gine’s oil level and what oil to use. If you get a blank look, then be con­cerned. You will strug­gle to kill an air- cooled 125 like the XT, but even an en­gine this solid can only take so much abuse. Al­ways in­spect the chain and sprock­ets, I’ve seen 125s ar­rive with bro­ken chain links and the own­ers didn’t spot it – and one was even com­ing in for an MOT!

“When it comes to the chas­sis, you have to ex­pect the bike will have been down the road, so it is a case of how hard. Bent bars are very com­mon, so check for this on a test ride, and oc­ca­sion­ally wheels and head­stock bear­ings will need chang­ing, but this isn’t very com­mon. In gen­eral, 125s don’t wear bear­ings or sus­pen­sion units as they don’t do that many miles, but forks can get bent or twisted in the yokes. “Nine times out of 10 the elec­tri­cal sys­tems are OK on a Ja­panese brand, but the Chi­nese 125s can have huge elec­tri­cal is­sues. Al­ways check the lights, horn etc work and per­son­ally I’d avoid a cheap Chi­nese bike as the spares sup­ply can be an is­sue. If you buy a Yamaha you can al­ways get the spares, some­thing that isn’t al­ways the case on a ran­dom Chi­nese brand bike. “If you want a bar­gain, look out for one with a blown en­gine, buy it cheap and then get a used mo­tor for about £200. Swap­ping them is easy and there are loads of 125s out there this can be done on.”
