Hi I will be looking to change the tyres on my TDM 850 for the new season (once weather finally improves). The bike currently has Bridgestone Battlax BT45R tyes front and rear 110/80-18(front) and 150/70-17 on the rear these tyres are old and worn and brick hard to boot. I have also found the bike to be guilty of tram lining quite badly and wondered what my options would be should i go for a wider front to cure the tramlining and a softer compound for grip etc . If anyone could reccomend a tyre size /type and manufacturer for this type of bike i would be very grateful.

Hi new to the site .Recently bought a my2000 TDM 850 twin ,great big bike, it needs a new chain and sprockets .i have found it has an exceptionally long first gear which makes it very lurchy at junctions etc and requires feathering of the clutch constantly on removing the chain/sprockets have found it has 17 tooth (front) and 43 rear sprockets. can anyone tell me what the standard ratio should be? the previous owner has changed the ratio to bring the revs down at cruising speeds as he had a long commute.
