Upgrade to Gen5 frame
Highsided my Gen4 pretty badly last race weekend. Bike went into wild roll at 140 km/h, everything is bent including swingarm and broken frame.
Now I'm thinking to upgrade to Gen5 frame.
My Kawa dealer makes me zero profit prices this time and why not go with gen5 frame and adjustable rake angle bearing collars?
I read that gen5 engine fits into gen4 frame.
Have not done much part number comparing jet, only that steering stem bearings are same, meaning I could possibly use my spare complete gen4 front end.
Here my initial questions:
a) As I buy new frame, then I need steering collars (inserts for bearing outer races). Are OEM collars non-excentric and make 24 degree rake? And kit collars are excentric (2 choices 23/25 and 23.5/24.5)?
Who has raced kit collars, how does 23 or 23.5 degrees feel compared to OEM collars?
Intrested to buy kit stem collars.
b) Does Gen4 swingarm fit into Gen5 frame?
Gen5 swingarm is hard to find.
c) If it fits, then is gen5 swingarm better/stronger?
I know it is little longer.
d) If using Gen4 subframe (with Gen5 frame), then does seat heigth change significantly?
Looking for all related infos about possible issues or/and why it could not be possible to do.
Gen4 race: high spec.
