Swing Arm Type 7

Fits: SUZUKI GSX250R

Japanese Webike user

4/5

Rear movement is improved.

I ordered Type 7 from Gun coatOption and received it in about 4 months.
When you hold it, you will see that it is light, about 2 kg lighter numerically.
OEM is Steel Horn Pipe and this product is Material:The stiffness is also considered to have changed because of the figure-of-eyes cross-section of Aluminum.

【attachment】
I asked the Shop to install it at the same time as KOOD's Pivot shaft.
Replaceable from OEM, no new parts required.
Also, it may be an individual difference, but the OVER exhaust bracket seemed to interfere with the Swing Arm and the OVER TT-formura RS, so an additional Spacer was inserted.

Quality, texture
In Gun coatOption, it is Black with Luster and looks much better than the OEM Horn PipeSwing Arm.
The Chain Adjuster also looks cool, but it is a pity that the Axle Block is made of solid wood.
Alternatively, there may be an option to purchase as Repair Parts and color anodized aluminum by yourself.

Ride comfort
We often hear that lightening the underspring is several times more effective than the overspring, but for simple overspring weight reduction, removing Gasoline is the quickest way to go.
We did not feel that a 2kg reduction in Swing Arm weight would make a difference in the behavior of the full Tan condition and on the verge of missing Gas, nor did we feel any difference in the push/pull of the vehicle body.
In the case of # of fuel quantity, you mainly feel the lightness of Handlebar and the lightness of the turnaround.

In theory, the Swing Arm should move more easily in response to changes because the inertia around the Pivot axis is reduced.
Just like when you hold a # stick and swing it up and down with just your wrist, the heavier stick requires more force in Timing to raise and lower it.

After running, we experienced a decrease in Rear thrust due to bumps and an improvement in Rear traction when exiting the Corner.
(Suspension setting unchanged)
Probably due to reduced input to the suspension during contraction, reduced change during extension and contraction, and improved responsiveness of extension and contraction.
Although it was Type 7 without Stabilizer, it seems to benefit enough for city driving and touring. View detail

Rear Sets with excellent cost performance

I bought it because the texture of Normal step was not good enough.

The Grip is also strong, making it easier to secure the outside foot load.

The quality is also quite high, but I think it is inferior to the same manufacturer's Large Motorcycle Rear Sets.

The installation process will take about half a day for a person who is not familiar with it. The Instruction Manual is also a bit of an "about".

This is a recommended part because it makes the motorcycle look all the cooler. View detail

Sprocket Cover

Fits: HONDA CB1100RS, HONDA CB1100EX, HONDA CB1100

4/5

Engraved Shift does not match the 10-13 model

[How is it used? I replaced it in conjunction with the introduction of the company's Light clutch kit.

Was the installation difficult? All I had to do was remove and replace the OEM, but it took me about 3 hours (including cleanup) to clean the accumulated ChainGrease dirt and polish the parts exposed by removing the OEM resin cover, as well as to replace the light clutch kit.

How was your experience with it? It is the self-satisfaction of Dress-up.

[Included Parts:were they on? Gasket and other necessary parts are included.

[Was there anything that disappointed you? I'm considering filling it with Bolt.

[Notes] In the product description of this site, the car model is -13, but on the Manufacturer's website, the car model is for 14 years or later. This is because Shift up to 6-speed is stamped on the product (according to the answer we received from the manufacturer). We have a 2010 model (5-speed), so I would like to hide the 6-speed indication by masking, etc. when the car is inspected. The installation itself was Large sturdy even after -13 years. View detail

Light Touch Clutch Kit

Fits: HONDA CB1100EX, HONDA CB1100, HONDA CB1100RS

Japanese Webike user

5/5

It's definitely lighter.

[How is it used? The clutch was originally heavy, but after replacing the handlebar, my hand started to reach its limit after about 3 hours of riding. We wanted to lighten the weight as much as possible, so we installed a new clutch.

Was the installation difficult? Together with the replacement of the company's Sprocket cover, which was also purchased, it took 3 hours, almost all of which was spent cleaning and polishing parts. The work itself is nothing to write home about (Fluid replacement is necessary).

How was your experience with it? It is clearly lighter. To put it bluntly, I was not expecting this, so I am satisfied. I was not expecting it to be so light, but I honestly feel that it is larger than I expected. I can feel the bumps by touching it with my hand due to grease sticking to the push rod.

[Included Parts:were they on? The minimum necessary items such as the Gasket are included, but the Spring and air bleeder in the Release were purchased separately as OEM new items.

[Was there anything that disappointed you?
Not particularly
I haven't been on it for 3 hours yet, but my expectation of improvement is Large. View detail

TT-Formula RS Full Titanium Slip-On

Fits: SUZUKI GSX250R

4/5

Lighter weight and improved throttle response

This is an impression with K&N's Filter and SP Tadao's PowerBox installed.
The assembly was requested to the Shop at the same time as the OVERSwing Arm for the one-year inspection.

[Weight]
It weighs about 2 kg less than the OEM Exhaust System.

[Sound Quality]
The thump-thump feeling during idling increases, and the sound becomes more Race ish before the power band.

[Volume]
It will increase. If you do not like this, it is better not to replace it.
This is the Level where you have to be careful in residential areas and you will want earplugs (Type with holes) for long-distance, high-speed touring.
Please keep in mind that the official introductory video does not turn to Power band, so please keep this in mind if you include it in your selection candidates.

Outputs
The throttle response is better, probably due to the lower exhaust pressure, and the feeling of shortness of breath in the latter half of the power band that was felt with the OEM exhaust system is considerably reduced. Before the replacement, the engine was screaming from 8,000 rpm, but after the replacement, I do not feel any strain even if I turn the engine up to 10,000 rpm (must be due to the filter). (There must be some influence of Filter)
In addition, the speed is higher than expected even when driving the same way as before the replacement, which suggests that the output Torque is improved from mid-range RPM onward.

I have heard that low speed Torque drops when changing to Other Brand Product, but immediately after the change, I felt that Power increased even at low speeds. After multiple runs, the Torque dropped slightly near the Idling area, so I assume that the fuel condition changed as a result of learning.
(AfterFirea sometimes appeared at medium RPM→low RPM with AxelOff, so the fuel mixture was not optimal)
I will try to take a power curve with Timing of Sub computer introduction. View detail
