Hard to select 1st gear - BMW Motorcycles

The problem could be worn cynlonizers on gear 1and2 or sleeve for 1st and 2nd gears

Sounds very much like it - not sure if it is a hydraulically operated clutch or cable... Check the fluid level if hydraulic
There may be some adjustment that can be made if it is cable operated

If the clutch is a problem you will have difficulty selecting 1st only as the gears would be spinning from the engine revs.. I would say that the front input shaft (clutch shaft) bearing is failing allowing miss alignment of the synchros and not allowing proper engagement of the gears synchro rings. It means removal and repair to the gear box so the clutch can be inspected while the box is out.

gearbox but you knew that, could be various inside needs inspection, if any rattling then there's loose metal in there. this might give you a bit of insight into gearbox.../www.dansmc.com/gearbox.htm

hey shane my recommendation is to replace the gears 1st and 5th and not to my knowledge is that a common problem to break gears like that you have to shift hard with out clutch ( power shifting )

good luck.

Maybe not your answer but.If the bike has sat around for a while,the clutch plates can stick together.Not all,but some.This makes gear selection hard and as you describe,once things warm up,it gets better.When I said about sitting around,I meant for a period of a few months or so at one time.Hope this helps

James, let off the gas when shifting, especially in 1st and 2nd gears.

If the clutch feels firm with no play u may have worn syncronizer's in the trans, take it to trans shop and have them road test it, they will not charge in most cases.

i'm unfamilar with the exact car but it sounds like part of your gear selection linkage is broken. This would be the part that is used to select the gears you can't select. I have seen some cars that use two cables, one for 1st and 2nd gear and the second for 3rd and 4th gear. I have also seen cars that use metal rods from the shifter to the transmission much like the cable setup, one rod for 1st and 2nd gear and the other rod for 3th and 4th gear.

Hope this in some way helps.
