K-Dirt Titanium Slip-on Exhaust (Motard Type) Minimum Baffle Mounting Type

Fits: YAMAHA TT250R

1/5

Satisfied only in terms of weight reduction.

Purchased for my TT250R, the OEM comparison exhaust system is 3.9kg while this one is 2.2kg, which is a weight reduction of 1.7kg.
OEMExhaust System parts are still available, but they cost about 60,000 yen, so Other Brand Products may be cheaper in many cases.

After installing the Fee Ring, it seems that the engine simply runs better, probably because there is no catalytic converter. The power at low rpm is less, but at high rpm it seems to be more powerful. I don't feel that I was particularly particular about the performance, and it would probably be possible to achieve the same performance by installing a simple cylinder of the same diameter.

What was very disappointing was the warranty. The middle bracket was completely broken off from the weld and damaged in 8 months after less than 10,000 km of purchase. I use it more than 90% for on road touring. I only drove it once on a Flat forest road. No falls.
I inquired if there was a warranty, etc. Warranty is limited to two weeks, so pay up." An exhaust system that breaks in two weeks is probably a design error, not a warranty. Personally, I think that a product that can not last for one year on the road is defective. It is nice to be able to buy a new Exhaust System for TT250R in this day and age, but the strength of the Exhaust System should be examined and tested.
The installation was done after temporarily fixing and determining the Layout, and it does not appear that an excessive load was applied.

YOSHIMURA offers a 2-year warranty. To be honest, there is no Full Exhaust System with only 2 weeks warranty. 2 weeks means that you may or may not do any touring after installation.
Next time I will not buy Kay TwoTEC products. I would not recommend them to others from a warranty standpoint. View detail
