In the time since I tried a BeezDeals fender lift I decided on redrilling the fender instead. If I were to buy a fender lift again, this one looks like a much better design than the BeezDeals one and it is what I would try: K-SPEED-CT45 Front Fender Upper CT125 . The other kits I've seen have flat brackets and use a ton of hardware, where this kit looks better designed to contour to the forks and some of the hardware is integrated with welds which makes it simpler but also *might* give better clearance from the tire.
I was looking at this fender lift this morning. Thinking it's worth a try to avoid drilling. This is a great thread! Just got my bike a week ago and I really want our snow to melt!!!

What is the problem/complication with the fender lift? I'd like to avoid drilling, but if that's the solution that works best, I guess I will follow along with everyone else.

I'm also thinking that the Kajima fender is a lot more the way I'd like to go. Any experience with that?

At least some of the fender lift kits pinch the fork boots, put hardware close to the tire, and result in a gap between tire and fender that is larger than what might be aesthetically pleasing compared to the stock gap on a CT90 or CT110.

No experience with the Kijima fender but there is also a Diablo tall fender that mounts the same if you're looking to do some comparison shopping.

When I emailed them (mentioned earlier in this thread) a dealer in NZ said they would indeed ship it if you wanted to buy the part.
"CT125 FRONT GUARD RISER BRKT" cost is $60 NZD before shipping and tax. You can email parts@achonda.co.nz for it.
It's made by Smith Attachments in NZ, but that manufacturer will not sell direct.

Awesome to know.

It’s also a bracket that they use in NZ and not that the fender is different?

Correct, they use a riser bracket. Honda NZ start with stock bikes and convert them with a farm bike kit of accessories they've put together. It is not a different production model or anything like that.

Makes sense.

I assume the NZ bracket doesn’t cause issues as the other aftermarket ones.

It would be worth asking the parts person. It looks like it's the same as the other aftermarket riser brackets, just silver. Maybe it uses less obtrusive mounting hardware though.

The farm kit includes different gearing that makes the speedometer and odometer inaccurate, as well as causing an ABS error. They don't reprogram the bikes to compensate for the changes because they're "for off road use" while also being "road registerable". Conflicting info. I wouldn't trust them to have everything perfectly sorted out.

If I go with Shinko 244 2.5 front and 3 back do I need new tubes? If so, how do I determine what size I need?
Thanks!

They are made from rubber, they will conform to the tire. Tube size is like hand grenades or horseshoes............close counts.

It's recommended that you replace the tube each time you replace the tire, doesn't mean you have to do it, especially if your tires have low wear. Tubes wear with tires. If you're going through the effort to replace a tire, it's cheap insurance to also replace the tube.

Tube sizes are usually a range, they will say on them what size tires they're good for. The stock tubes are good for 2.50-17 and 3.00-17 (they say 80/90-17 on them and 80 mm is ~3.15 in).

Using too small of a tube results in stretching the material thin, making it more susceptible to damage.

On the first page FAQ's it states:


What combinations are known to work without modifying the bike?
  • Max 2.75" on the front (80/19-17) with no rub, 3.0" with a tiny bit of rub at speed.
  • Max 3.0" on the rear.

I was wanting to know if the OEM 80/90-17's were closest to a 2.5" or 2.75" tire? Where the FAQ states "Max 2.75" on the front (80/19-17)" I'm assuming it was a typo on the 80/19-17 and was meant to say 80/90-17 which implies the OEM 80/90's are around or are 2.75". Am I interpreting this correctly?

The OEM tires are 80/90-17 where 80mm is ~3.15 inches. What makes the difference is knobby vs dual-sport or street tires. The knobs protrude far from the tire carcass making it so that a knobby tire with a smaller size on paper is actually the same or larger in external dimensions than a larger size (on paper) street oriented tire. Measurements vary quite a bit from tire to tire.
"DaBinChe" on YouTube has a few videos illustrating how different tires for the CT125 compare in size which is a good example for illustrating it:

How much do OEM tires cost typically?

I'm going to be riding at least 80% in town, so I don't see a reason to switch from the OEM tires. 5400 miles on them now, rear is a worn but functional, going to change it. Front looks pretty good, not going to change it yet.
