Also the Repsol has DID rims rather than the Spanish Morads on the STD bike. DID's are miles better quality.

Told me at The Scott that he's on holiday this week

I'm currently running 40cc oil in 5 litres of petrol which is about 125:1 (when your running in go with 100:1 - 50cc in 5litres) I only use the best oil though - Castrol Power 1 - fully synthetic. Here in the UK many use the more widely available oil in a blue and yellow bottle which is vastly inferior. It carbons up and gums up the inside of your engine - well marketed crap ! You're only using half the amount of oil that other 2 strokes use so you can afford the best. Also the main bearings are lubricated from the gearbox oil so you're only lubricating the main bearing (which is directly in line of the incoming fuel/oil mix) and the cylinder bore/piston. Keep on top of the gearbox oil changes. If you're worried - remove the exhaust front pipe - you can then see the piston with a torch and wipe your finger on the piston and see how oily it is with 125:1 - you'll be surprised. Great bike - keep on top of the rear suspension link bushes, they don't last long but they are as cheap as chips so you can afford to replace them regularly. Tip - get them from your local bearing suppliers - SKF part numbers are usually stamped on to the outside.

I had one of the stiffer sidewall tyres on for one trial and it split all the way round the sidewalls. This was replaced by a softer sidewall variety and that one won't hold pressure and it's not punctured ! Tried it on 2 different bikes (different wheels) and it stays up all week until I reduce the pressure and ride a trial on it then it goes down during the trial? Had it under water and no leaks anywhere. Can't remember the numbers as my bike is not at home so I can't have a look but it was called a Gecko. Steer well clear !

Sorry I misunderstood what you were looking for. I gave you the part numbers for the linkage bushes. My swinging arm bushes were like new and didn't need replacing. If you knock the old bushes out you may be able to find the SKF part numbers stamped around the outside - that's how I got the numbers for the others. You'll need a magnifying glass to read them. If you go to http://www.ossamotor.es/EN/documents.php you can download the parts diagram. On pages 4 for Chassis you can see the parts Item 9, 14 and 15. Item 9 is an Ossa specific part but 14 and 15 are Glycodur bushes which is an alternative to SKF. Item 14 - 202315 is the 20mm Inside Diameter, 23mm Outside Diameter and 15mm Length of the bushes. Measure to confirm. Item 15 - 202321.5 is 20 x 23 x 21.5mm with flange. Permaglide is another trade name for this type of bush. Happy hunting

You need 4 off SKF part number PCMF161817E for the swinging arm (item 3 on the parts diagram) plus one more for the chain tensioner if you need it (and you likely will !) Also 4 off PCMF 161812E (Item 39) Cost me £1.50 each about 2 months ago from local bearing factors. I've drilled and cross drilled my pins to allow PTFE grease injection via a special adaptor that screws into the screw hole in the end of the pins. If the pins get dry, they rust and the rust wears the bushes. p*** easy to replace - I made a pin type tool on the lathe to tap them back in. They're delicate and can twist when pressing back in even though they aren't particularly tight. Good Luck.
