Definitely seem to be one of those bikes that people have a soft-spot for, based on the replies so far...
Spoke to Tim the SL guru last night, and he's stirred up thoughts of 150 kits and methanol, and... Hmmm... maybe we'll just get it running first!
Although, does anyone have a SL125 motor they're willing to part with?
Gezza, As kids we all had four stroke Hondas (back when 4-stroke meant quiet and relaible - how things change...), so there's been a long list of old Hondas in my past... Though, I only owned two of them myself before I discovered the better Japanese brand.
The SL100 is sitting next to my two XL175s (one racer-to-be and one resto-to-be) and now an 87 CR125RH, so it won't feel too lonely...
As to the exact age... I dunno...
Someone help?
