Hi Monty, i own a Solo 210 engine which is the predecessor, this might help you as i buy my belts of ebay as loads cheaper even for goodyear, If you measure all the way round the outside it gives you the length, ie :- mine measures 559mm (hopefully same as yours) and i use a "Goodyear poly-v 220j 559pj" but a 14 rib, if you look them up on ebay they offer 3-24 rib's so may cover yours in them.

kiwi k Posted October 13, 2016 Share Posted October 13, 2016 Like posted earlier measure all way round the edge and rib amount and put up dimensions and we'll go from there Quote Link to comment Share on other sites More sharing options...
Dariuszk24 Posted October 14, 2016 Share Posted October 14, 2016 Because its few ratios your engine Do like says kiwi k Take pice of string and wrap around the belt ,cut string in place where string joining,now take string and measure length we need also know how wide your ribs are . For example 9.5mm, 4.5mm, 3.5mm or other In here you have web side what you can get http://simplybearings.co.uk/shop/Products-Poly-V-Belts/c4747_5339/index.html But if you decide to order mark you want only contitach this are the best!!
