Shaving the Seat – DIY

Shaving a motorcycle seat is the easiest and safest DIY way to lower a motorcycle.  This process involves removing the seat cover, shaving foam off the bottom, and re-installing the seat cover.  Done well, this method does not reduce comfort, and retains an OEM look.

The foam should be shaved from the sides of the seats especially towards the front. ideally, once you shave the most foam from the front sides of the seat. Shaving foam from this area makes reaching the ground easier compared to other areas of the seat without reducing comfort.  Removing foam from the middle seat will slightly lower the seat, but will reduce the cushioning that seat provides.


Pro’s:

Reduce seat height up to 2 inches

Can maintain comfort and OEM look

Maintains performance of motorcycle

Lowest cost option

Con’s:

Shaving seat incorrectly may reduce comfort

The end result may not be pretty

 

Time: 2 – 3 hours

Difficulty: 3/10

Cost: minimal

Low Aftermarket Seats

For riders trying to find the easiest way of how to lower a motorcycle, buying a shorter seat is the answer.  Aftermarket seat manufacturers such as Corbin, Sargent, Seat Concepts, and Touratech make seats for certain bikes that are up to 2 inches shorter than OEM.  These seats are generally designed with comfort and style in mind, and could be at your doorstep in a few days.  


Pro’s:

Plug and play – easiest way to lower seat height

Quality fit and finish

Known level of comfort – most aftermarket seats are designed with comfort in mind

No downtime from riding – use your stock seat now, replace when the new one comes in

Con’s:

Price- expensive compared to shaving a seat

 

Time: <1 hour

Difficulty: 1/10

Cost: $200-$600

 

Seat Kits – New foam and cover for current seat

Some companies such as Seat Concepts offer kits which include new foam and covers for the seat pans already on your motorcycle.  These kits can lower the seat height up to 2 inches vs stock.  At the time of writing, seat concepts also offers installation service for an additional $25 on top of the seat kit price.  This way, you send in your seat, they install the kit, then a new seat shows up at your door a few weeks later.   

 

Pro’s:

Competitive prices compared to aftermarket seats

Corbin, Sargent, and many other companies offer custom motorcycle seats.  As they’re custom, these can be designed to be lower, with greater comfort using more advanced (see: pricier) materials, and to look however you like.  Some manufacturers also can mold seats to conform to your body, improving comfort and allowing for support where needed without significantly increasing seat height.  

 

Pro’s:

Looks – great, just the way you want them to

Comfortable – can be molded specifically for a rider

Getting your suspension tuned by a professional

 

Getting a bike’s suspension set for your weight improves handling, braking and acceleration; all key aspects to most safely controlling a motorcycle.  

Even a cruiser riders stand to benefit from such as setup, and in my experience, is well worth the ~$40 most suspension technicians charge for a 1 time setup.  As part of the suspension setup, a train mechanical sets ‘sag’, a setting allowing the bike’s suspension to function in the range it is most effective.

Alright, that’s nice and all, but you may be thinking I was trying to figure out how to lower a motorcycle, how does this help?  Suspension technicians start by setting  ‘sag’ to the bottom of its recommend range, helping keep one’s bike from being unnecessarily tall.  Adjusting suspension preload, and changing springs can also make a difference.  As suspension tuning is one of the more complex aspects of motorcycling, this is an area I recommend entrusting to a professional when starting out. 

In the SF Bay Area, there are a number of reputable suspension tuners including Catalyst Reaction Suspension Tuning in San Carlos and Evolution Motorcycles in Santa Clara, as well as Dave Moss Tuning, who often teach suspension courses at Moto Guild in San Francisco.


Pro’s:

Can slightly reduce seat height

Improves safety – makes the bike handle better and react more efficiently to your inputs

Con’s:

Going to a suspension shop or bike night, being around motorcycles and experienced riders could be intimidating


Time
: ~30 minutes

Difficulty: 1/10

Cost: ~$45

 

Lowering links aka. dog bones

Lowering links physically lower the rear suspension bringing it closer to the ground, which in turn reduces the seat height.  However, this also reduces ground clearance, which may cause problems going over speed bumps and dragging hard parts when cornering at higher lean angles.  As most new riders are unlikely to be pushing motorcycles anywhere near lean angles where hard parts start dragging, the increased confidence of being on a lower motorcycle may be worthwhile.  If just cruising around, a new rider would be unlikely to notice significant difference in handling.  

Additionally, lowering the rear suspension using lowering links drastically affects the handling of the motorcycle.  The suspension was designed with a certain geometry from the factory.  As such, to help the suspension work as well as possible with lowering links, one should also lower the front forks in the triple clamp the same amount the rear was dropped.  

Additionally lowering a motorcycle with this method may lower the bike to the point that an aftermarket kickstand is required.  Given then downsides, I rarely recommend this route to friends who ask about how to lower a motorcycle.  

 

Pro’s:

Lowers motorcycle .5 – 2 inches

Con’s:

Negatively affects handling of the bike, significantly

Decreases ground clearance

May require shortened kickstand

Most labor intensive  lowering method

 

Time: 1-2 hours

Difficulty: 4/10

Cost: ~$80(parts), 1-2 hours of labor at a reputable shop
