stay with the 748 simon just add some quality bling if you want to spend some money or keep as it is and get more track time in and just enjoy the bike..dont get caught up in needing a bigger bike or carbon this or that...enjoy the machine as it is..its all you will ever need...........
The serves is coming up in the end of may so I mite keep it for another year or so and get it to a hi standard, like you lots bikes! That look like you don’t ride them.
Stick with the 748 mate, i have the same and havent had any problems with it, just had it serviced in Jan/Feb time and didnt set me back too much, like the others have said just bling it up a bit!!
If you buy a new bike, it's just a more expensive platfrom to bolt stuff onto and you'll end up buying bling kit anyway...
Anyway, 748's rock the world. I recently had a 749R for a few hours, awesome bike, but not nice enough for me to be finding a spare 14K. (cos I'll not let my 748 go...)
Cant really beat a 748 once you've got it all sorted - find a good bike mechanic / dealer who knows Ducs and put it it for a full service and checkover - anything that is wrong can be fixed or replaced, and if looked after they are generally pretty reliable once a few niggles have been sorted out.
I havent ridden the 749, and am sure its a nice bike - but go outside now and look at the 748 - can you honestly tell me you're going to get a better looking bike than that ?
