KONA BIG HONZO | More Freedom for Mountain Play with Semi-Fat Tires

The reassurance of being able to hit the trails without hesitation. 27.5+ tires expand the possibilities for free mountain play.

The KONA BIG HONZO is a playful hardtail MTB featuring 27.5 x 2.8-inch semi-fat tires.

It's a versatile bike that handles everything from trail riding to forest road touring and bikepacking, naturally making you want to explore "deeper into the mountains."

Thanks to the high grip and stability unique to semi-fat tires, you can confidently choose your lines even on rough terrain with rocks and roots, making it easy to control even for those new to MTBs.

Combining a lightweight yet durable 6061 aluminum butted frame with KONA's well-balanced geometry, it's designed to make climbing and descending naturally enjoyable.

Furthermore, it comes standard with a dropper seatpost, offering great freedom on descents and technical sections, making it a complete package capable of serious trail riding.

It's highly recommended for those who "want to start MTB but are a bit scared," as you can ride without worrying too much about small gaps or tree roots. Its high stability gives you the impression of naturally getting accustomed to the trails.

Moreover, it rolls lighter than it looks, making it quite compatible with forest road touring and bikepacking. It naturally fits into a leisurely style of riding with luggage.

The standard dropper post is another major attraction. Since adding one later can be costly, KONA's completeness in having it included from the start is truly impressive.

MTBの楽しさを詰め込んだハードテイルバイク

MTBからスタートしたブランドであり、今もなおMTBラインナップをメインとするKONA。

中でもアルミハードテイルバイクは「初期費用と維持費を抑えて、楽しくマウンテンバイクで遊ぶ」というニーズにしっかりと応え続けてくれています。

そんなハードテイルバイクの中でも人気を集めているのがこの「BIG HONZO」

登って下って、山を余すことなく遊び尽くせるモデルになっています！

強度に定評ある6061アルミフレーム

フレーム素材は強度・耐久性に優れる6061アルミを採用。

素材だけではなくパイプ同士をより広い面積で溶接、ガセットで補強したりとオフロードバイクとしての充分な耐久性を有しています。

KONAの6061アルミフレームはバテッド処理されており、強度計算を行った上で不要なところは薄く仕上げてあるので軽くしなやかな仕上がりです。

トレイルの走破性抜群！！27.5×2.8インチの27.5+タイヤ

BIG HONZOシリーズといえばまず特徴的なのがセミファット / 27.5+ タイヤ。27.5×2.8の圧倒的なボリューム感は小さなノブ+面の広さでグリップする設計。

木の根っこや突き出た石など、目まぐるしく変化する（それが楽しいんです）トレイルの路面をしっかりと面で捉えてグリップする事が出来るのでまだトレイルに慣れていないMTBデビューにオススメしたい⇒毎年大人気というわけなんです。

ノブの小ささから転がりも軽く、前述のフレームジオメトリも相まってオフロードを繋ぐバイクパッキングバイクとしてもオススメ◎

トレイルで効果高いサドル高を手元で操作できるドロッパーシートポスト標準装備

最早MTBのマストアイテムとなったドロッパーポストも標準装備。手元レバーでいつでもサドル高が調整出来、安全かつ楽しくスムーズにトレイルを楽しむなら無くてはならない存在です。カスタムで取り付けると費用が嵩むポイントでもあるので、標準装備は本当に嬉しいところ。
