Hey Sebastian,
I looked but could not find an answer to your question.
Some Notes: The T100 Bonneville has a 17 rear wheel. Our rides have a 15 inch rear wheel. A clearance issue might be one reason why not.
Are the swing arms the same width at the rear drop outs? This would be THE limiting factor as the fender can be modified.
Does the chain ring on the T100 reside the same distance perpendicular to the wheel's longitudinal line as the speedy's? Gotta have the chain line straight.
Having measuring tool in hand you could visit dare I say a dealer? And measure away. Brent at
Newspeedmaster.com or Mike at
Bellacorse.com have an ear you might bend.
